Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
After some WebGL application crashed the proprietary amd video driver - plasma suspended window decorations etc. - after trying to activate with alt+shift+f12 plasma crashed
- Unusual behavior I noticed:
WebGL app in firefox [aquarium demo] crashes the display driver and plasma with it - results in display corruption and the crash of the window managers opengl capabilities
- Custom settings of the application:
Use of the proprietary amd video driver 11.8

The crash can be reproduced some of the time.

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