-- 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".
