Sentry Crash Report:

Description Vojtěch Weiss 2012-01-20 06:25:26 UTC
Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:

Once I lock my desktop and leave it for some time with screensaver running, plasma crashes after some time. I think that it has something to do with latest nvidia driver (installed from repository). I can repeat this situation everytime I lock my desktop.

The crash can be reproduced every time.

-- Backtrace:
Application: Shell plochy Plasma (plasma-desktop), signal: Segmentation fault
