Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Using Kubuntu 11.10 the Plasma desktop crashes repeatable after every login without any further action (except autostarting a few applications: Skype, Thunderbird and Kopete).

The crash can be reproduced every time.

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