Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Can't remember exactly since I was not doing anything special.  I think I was just closing a Dolphin or Terminal window... but not sure about that. Sorry for not being more precise.

- Unusual behavior I noticed:
Plasma crashed with some "bugs" in the display, meaning with lines and squares displayed ramdomly on my 
screen for a few seconds.

- Additional information
I am using Ubuntu 11.10 with Unity, on top of which I installed KDE ;)

The crash can be reproduced some of the time.
