[Bug 1053910] Re: My plasma-desktop is critically sluggish, panel and kdialog reacts after few minutes because of dbus Timeout problem

[kenorb]

When running it manually again using the same command line, I've this
error:

 /usr/bin/python /usr/share/kde4/apps/muon-notifier/releasechecker

Probably, because I'm behind the proxy.

Bug description:
  I've been sent from pillar to post from almost few days, spent already
  few days investigating my Ubuntu slugginess right just after install,
  so I hope this report is now in the right place. I don't have time for
  this, I really need to work, instead of spending days fighting with
  simple usage of Ubuntu and reporting the bugs and receiving messages
  like 'this is not a bug of x', 'this is not a bug of y'.

  The bug affects affect in general plasma-desktop on Ubuntu.

  Some examples:
  Using Chrome which uses KDialog, any file upload takes minutes.
  KDialog timeouts after 25 seconds 4 times, makes it the whole minute to show up.

  Steps to Reproduce:
  1. Go to: https://code.google.com/p/chromium/issues/entry
  2. Click on: Attach the file
  3. Click on: Choose File
  4. Problem: Nothing happens.
  5. After 25 seconds KDialog appears.
  6. It takes another 20-30 seconds to fully load (still you can't click anything).
  7. After the whole 1 minute you can choose the file.

  Other bugs which I've reported related to KDialog:

  Against KDE KDialog:
  https://bugs.kde.org/show_bug.cgi?id=307049
  Status: "I can only guess from seeing the parts you posted, that there is a kded module blocking the D-Bus system. Please try disabling kded modules as described at http://kdepepo.wordpress.com/2011/05/11/troubleshooting-kded4-bugs/"

  Against KDialog it-self:
  https://bugs.launchpad.net/ubuntu/+source/kde-baseapps/+bug/1053869
  Status: this is only a small issue of bigger thing

  Other bugs which I've reported related to KDE plasma-desktop:

  Steps to Reproduce:
  1. Click on KDE "start" button
  2. Nothing happens.
  3. After 1 minute and 30 seconds you'll see the context menu!
  Some people say, it's better later, than never.

  Against KDE plasma-desktop:
  https://bugs.kde.org/show_bug.cgi?id=307048
  Status: currently ignored

  And finally against the DBus it-self:
  https://bugs.freedesktop.org/show_bug.cgi?id=55136
  Status:
  "This is probably the problem: there seems to be some sort of incompatibility
  involving Ubuntu's "dbusmenu" system and how it interacts with Qt/KDE
  applications. Please report this to the suppliers of the packages you're using
  (Ubuntu, Kubuntu, or any third-party dbusmenu or KDE packages you're using).
  I don't think this is a D-Bus bug."

  As well currently I can't do any launchpad upgrade or send any apport-collect, because of these annoying bugs:
  https://answers.launchpad.net/ubuntu/+source/apt/+question/202373
  https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1053861
  https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1053400

  So to not repeating my-self and pasting a bunch of strace, debug stuff (which you can access from the links above), the current status of this big Ubuntu and KDE bug as suggested from DBus support, is as follow:
  > (process:7387): GLib-GIO-WARNING **: Received property menu with type s does not match expected type o in the expected interface void DBusMenuImporter::slotGetLayoutFinished(QDBusPendingCallWatcher*): "No such interface `com.canonical.dbusmenu' on object at path /" 
  Please report this to the suppliers of the packages you're using
  (Ubuntu, Kubuntu, or any third-party dbusmenu or KDE packages you're using).

  So now I'm reporting it now against Ubuntu, as my reports against KDE,
  X, DBus failed.
