-- Information about the crash:
- What I was doing when the application crashed:
It crashed while I was using Google chrome on Kubuntu 11.04 with kde 4.6.4 (and today 4.6.5). It happens about 15 minutes after the login. It happens with no particular running application

The crash can be reproduced every time.
