Description Stefano Marelli 2011-06-26 06:07:12 UTC
Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.4 (4.6.4)
Qt Version: 4.7.3
Operating System: Linux 2.6.39-2-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:
logging in. Happens everytime. After the crash, the desktop is perfectly usable. Kmix crashes every time, it might be related
- Unusual behavior I noticed:
during the previous boots everything was fine until:
  - I updated the distribution (debian unstable, minor upgrades only, but can not check)
  - the computer hard crashed shortly afterwards, and I had to reboot. It is very uncommon for this system to hard crash. Happened while watching a youtube video

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
