Qt Version: 4.7.0
Operating System: Linux 2.6.35-30-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
trying to load my KDE

Black screen surrounding the application I'm using. The desktop won't load. All normal features won't load

The crash can be reproduced every time.
