Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.5
Qt Version: 4.8.3
Operating System: Linux 3.5.0-22-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:It seems like after almost every upgrade, my system breaks. Again upon startup, plasma-desktop crashed just when entering the desktop. Nothing changed since my last reboot, no apps, no new desktop widgets.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
