Description Kai Uwe Broulik 2013-01-12 13:05:22 UTC
Application: kwin (4.9.97)
KDE Platform Version: 4.9.97
Qt Version: 4.8.3
Operating System: Linux 3.5.0-18-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
I changed the window decoration from Plasik QML to Oxygen. When I hit apply, KWin crashes reproducibly and restarts then with the Oxygen theme.

Can be reproduced every time.

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault

Kai, can you run the kcm through valgrind?
