Description bugzilla.kde 2012-01-17 15:46:17 UTC 
Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-15-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Using my computer normally.  Nothing in particular triggers it, but it happens every few seconds, non-stop.

- Unusual behavior I noticed:
The KDE menubars flicker and then crash, I'm disconnected from the wireless network constantly, the KDE window decorations crash.  This happens literally every 15 seconds (at the most), and makes the PC completely unusable.

I've had to resort to using (shudder) Unity to escape this crap, as KDE is completely non-functioning due to this bug as of latest update.

The crash can be reproduced every time.

-- Backtrace:

New crash information added by DrKonqi

plasma-desktop (0.4) on KDE Platform 4.7.4 (4.7.4) using Qt 4.7.4

- What I was doing when the application crashed:
I booted ccomputer, logged into KDE with KDM, this happens every couple seconds.

- Unusual behavior I noticed:
KDE is unusable, wifi is unusable with KDE networkmanager in charge.

plasma-desktop (0.4) on KDE Platform 4.7.4 (4.7.4) using Qt 4.7.4

- What I was doing when the application crashed:
Tried apt-get update, apt-get upgrade, then re-login with kdm.  Same problems, possibly even worse now.

- Unusual behavior I noticed:
The network is disconnected every 3-5 seconds now, instead of every 10-15 seconds like I was experiencing before upgrading anything.  The entire KDE workspace crashes constantly as well, with menubars, window decorations, backgrounds, etc. going away (every 10 seconds or so, just about as quickly as it takes to restore it all after it crashes).
