Additionally, after importing Bookmarks from KDE3 Konqueror, all
bookmark icons are replaced with a questionmark on a white sheet. Yet
konqueror does not try to refetch them when visiting the page. Icons for
new bookmarks appear correctly.

keditbookmarks.
Maybe your kded4 crashed? Otherwise I don't really know what could cause
this, given that it works for me (on two different computers, with two
different versions of KDE)

Unfortunately, this is not the case here. Update does nothing. This
has been the case since 4.x. In 3.5 when you edited the bookmarks
and chose to "update all favicons" you could see the process travelling
each bookmark and updating. Now nothing happens.
So, we need to compare details. I am on Fedora 11+updates, and x86_64
versions with qt-4.5.3. What version of qt are you using? I remember
seeing some place that this could be a qt bug.

Confirmed for Konqueror 4.3.4 - but to me it seems to be several
different (but maybe related) bugs.
My view:
The favicons of the bookmarks are replaced with the question mark when
you import bookmarks or delete the cache or change anything else
concerning konqueror's bookmark's favicons
(~/.kde/share/apps/konqueror/faviconrc) because seem to be unable to
update - even in the address bar there will be only a question mark for
those favicons saved under your local favicon folder.
The only "clean" workaround seems to be deleting the local favicon
folder (~/.kde/cache-$HOST), the bookmarks you want to see the favicons
for (e.g. bookmarks bar beneath the address bar), restart konqueror (or
your whole system) and then adding the wanted bookmarks again one by one
(annoying!).
Favicons unknown to the system (not stored in your local favicon folder)
should not be concerned. If that is the case, you should additionally
delete your ~/.kde/share/apps/konqueror/faviconrc.
Im checking something else and will update this post, if necessary.

The workaround above doesn't do it for me.
Also tried it on a clean /home.

Confirmed on FreeBSD 8.0 / KDE 4.3.4. Clearing the icon cache only helps
a little bit. A few bookmarks will then update, but most will not, even
when the favicon is clearly showing in the URL.

I'm seeing this on my netbook (but I've never seen it anywhere else),
and am starting to have a look around.
To make sure it's the same issue, here is what I am seeing in Konqueror:
1) For the failing-to-load favicons, when switched to the tab whose
favicon doesn't load, the left-hand side of the url in the location bar
is flush with the left hand side of the location bar, whereas with
correctly-loaded favicons, the favicon is between the left-hand size of
the location bar & the url. Importantly, there isn't a favicon-sized
blank image there: there is simply nothing at all.
2) For tabs with the failing-to-load favicons, the tab does not contain
the favicon: just a blank, favicon-sized patch. (I'm not seeing the
"question-mark on a blank sheet" thing, though).
3) The failing-to-load favicons do no show up in the bookmark editor -
instead, a blank, favicon-sized patch is theree.
4) In the "Other Tabs" list, the failing-to-load favicons do no show up
- there is a blank, favicon-sized patch instead. *However*, sometimes
if I hover over one of the entries, its favicon *does* show up (in the
list), and stays until I unhover the entry. I haven't discovered a
pattern for when this works, though.
5) When switched to a tab with a failing-to-load favicon, the konqueror
app icon (i.e. the one that is shown in the window title & taskbar) is
set to a generic "globe on white background" icon, *with a tiny version
of the favicon in the bottom-right corner*. The favicon does seem to be
getting loaded correctly somewhere along the line!
Are people seeing the same symptoms as I am?
I've been hacking around inside keditbookmarks, and in the "if (role ==
Qt::DecorationRole && index.column() == NameColumnId) " block of
kbookmarkmodel/model.cpp, the KIcon returned, when I ask for a 16x16
pixmap, is blank (appears to be a 16x16 fully transparent image) for the
failing-to-load favicons, but correct for the others, so it may be a
problem inside KIcon (it has a special code-path dedicated to favicons).
The required image is present and correct in my kde-cache/favicons
folder with the expected filename; it's simply not being loaded, it
seems, or is being trashed elsewhere.
I won't have time to investigate further as I'll have to set up a kde
build environment on my netbook, which will take a while.

Woah! Simon! Your description of the bug is very precise and also very
accurate! I was able to verify all the points you make (Kubuntu / KDE
4.6.2). You also get special credits for your powers of observations in
4) and 5)!!! Yes, the missing favicons can amazingly be found in the
places you describe.
I hope those finding can help someone to get to the bottom of this bug
and fix it. Many thanks to the developers.

Ok, had a quick look into what's going on here, and (at least from
keditbookmark's point of view), it's to do with KIconCache not being
invalidated when a favicon is.
Sample run of keditbookmarks, assuming that the favicon for somesite.com
is not in /var/tmp/kdecache-<user>/favicons:
- keditbookmarks starts up, displays tree of bookmarks;
- Each bookmark has an icon (usually, for websites, the favicon for the site, in which case the icon starts with the magic string "favicons") that must be rendered;
- To be rendered, the icon must be loaded via KIconLoader;
- KIconLoader has a magic path for favicons, where it deduces the full name of the favicon image in /var/tmp/kdecache-<user>/favicons;
- This image is checked for in the KIconCache - if it is there, that image is returned and this will be displayed in keditbookmarks;
- If not, it tries to load the image from the /var/tmp/kdecache-<user>/favicons folder;
- If the image is not there - which is the case with somesite.com, then the image, instead of being null, will be a blank 16x16 icon (not entirely sure how this happens yet - will need to get gdb to cooperate in stepping through the code!)
- This image is then added to the KIconCache and will be used by iconloader for any subsequent requests for this favicon, until the KIconCache is deleted.
So essentially, as soon as keditbookmarks starts up, the current version
of the favicon - or a 16x16 blank if the favicon has not yet been
retrieved - is inserted into the KIconCache and this cached version will
always be returned when that favicon is requested. If the favicon
happened not to have been downloaded at this point, then we're stuck
with a favicon, even *after* the correct favicon has been downloaded.
One course of action that I haven't yet tried is to call
KIconCache::deleteCache() prior to each "emit iconChanged" in
lib/konq/favicons/favicons.cpp, but deleting the entire icon cache on
this seems like overkill. There doesn't seem to be a more precise way
of just removing specific groups of icons from KIconCache. We *could*,
instead of that, overwrite just the updated favicon in the KIconCache,
but we'd need to duplicate the KIconLoader::makeCacheKey which I'm not
keen on, and this wouldn't help invalidating any favicon overlays using
the old, invalid favicon.
Another approach might be to make KIconCache itself "favicon-aware" in
much the same way that it is currently "theme-aware".
David - a penny for your thoughts? ;)

Whoops - turns out that KIconLoader's mIconCache is actually a
KSharedDataCache, not a KIconCache - silly me! The above is still
(mostly :/) correct, though.
