I was reading a PDF and wanted to configure shortcuts. Konqueror
crashed.

I cannot reproduce the problem with random files and don't remember the
PDF I was looking at, but maybe the dump helps:

Like I said, I can't exactly reproduce with current 4.1.0.

But as soon as the binary Packages for FreeBSD are updated I will
upgrade to 4.1.1 and agressively press the configure-Shortcuts-Button
while reading lots of PDF :D

This happened while I was configuring choqok. I was setting the
prefferences when suddenly died.

I have some more info on this.

First, I'm attaching a valgrind log. This is from RKWard (also affected), and KDElibs 4.3.4. For reference, here are the relevant lines of KEditToolBarWidgetPrivate::initKPart() with the 4.3.4 line-numbering: 709 	709 // add all of the client data
710 	bool first = true;
711 	foreach (KXMLGUIClient* client, factory->clients())
712 	{
713 	if (client->xmlFile().isEmpty())
714 	continue; 
[...]
729     }

That is, the crash occurs while iterating over the factory's clients.
The only plausible cause (beyond utter memory trashing) is that there
are dead clients in the factory's list.

Indeed, using this thought, here are 100% reproducible (on this system)
instructions on provoking the crash in kontact:

1) Enable Popup-Notes in Settings->Configure Kontact.
2) Bring up the Popup-Notes window.
3) Bring some other window (e.g. Notebooks).
4) Disable Popup-Notes in Settings->Configure Kontact.
5) Now select Settings->Configure Toolbars.
6) Watch it crash.

I think the central point is that the popup-notes-part is first added to
the factory. In step 4) it is deleted, but somehow the pointer is still
in the factory's list.

For RKWard, explicitly removing parts from the factory in their
destructor appears to solve the issue (at least for the described way of
triggering the crash). But: Shouldn't this really happen automatically
(i.e. in the KXMLGUIClient destructor)? Am I overlooking something? I
wonder where else this leads to crashes...

I was using Kopete and clicked to configure shortcuts from a menu bar.
Kopete crashed. The error is hard to reproduce.
