Application: plasma-desktop (0.4)
KDE Platform Version: 4.5.90 (4.6 RC1)
Qt Version: 4.7.1
Operating System: Linux 2.6.31.14-0.4-desktop x86_64
Distribution: "openSUSE 11.2 (x86_64)"

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

Regardless of what I'm doing (even if I'm doing nothing), Plasma crashes at least once after I log in after around 30 sec. This behavior started with installing the KDE SC 4.6 RC rpms.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma-Desktop-Umgebung (kdeinit4), signal: Segmentation fault
