Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Shutting down Kubuntu. After pressing the log off/shut down button *the pop up* it will try to shut down and crash.

- Unusual behavior I noticed:
Once the pop up from Shut down/Log off button appears the back ground starts to crack *like a videocard that isn't capable of handelling a game.

- Custom settings of the application:
I do use a theme for the logon/off window and do have a fully customized kubuntu *the virtuallazation.. but nothing else really.

This problem happen just recently but don't know what caused it.

The crash can be reproduced every time.
