Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
At logging out, plasma crashes systematically.

- Unusual behavior I noticed:
Plasma crashes and a empty desktop appears with default theme.
Window borders disapears.

The crash can be reproduced every time.

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