Bug 300955

Application: kwin (4.8.3 (4.8.3) "release 501")
KDE Platform Version: 4.8.3 (4.8.3) "release 501"
Qt Version: 4.8.1
Operating System: Linux 3.1.10-1.9-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

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

Dolphin was freezing and KWin helper appeared. With Task manager I closed all three Dolphin-related windows, including KWin killer helper. Shortly after that KWin crashed.

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
