Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Linux Mint 12 Lisa

-- Information about the crash:
- What I was doing when the application crashed:
Logged out of KDE
- Unusual behavior I noticed:
Kwin closes, making all the windows decoration disappear, then Plasma crashes.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Outil de gestion de fenêtres Plasma (plasma-desktop), signal: Segmentation fault
