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 i686
Distribution: Ubuntu 11.10

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

I was experimented with oxygen appmenu and decided to get default kwin decoration back. But menu didn't appeared. To reload plasma I killed plasma with kquitapp in krunner. And after typed plasma-desktop — it crashes again and again.

The crash can be reproduced some of the time.

-- Backtrace:
