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

starting my system Kubuntu 10.04 LTS

this is reproducable nearly every systemstart,

think it happens since the (very?)last security update

The crash can be reproduced every time.

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