Bug 291079

Application: kde4-window-decorator (0.0.1)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.0
Operating System: Linux 3.1.6-1.fc16.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
Decorator crashes a login, then again at logout.  In general, the screen has a lot of artifacts, especially leftovers after switching desktops.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Window Decorator (kde4-window-decorator), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
