Application: kwin (4.5.71 (4.6 >= 20101005))
KDE Platform Version: 4.5.71 (4.6 >= 20101005) (Compiled from sources)
Qt Version: 4.7.1
Operating System: Linux 2.6.34.7-0.3-desktop i686
Distribution: "openSUSE 11.3 (i586)"

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

I was holding down Alt key and pressed Tab repeately (using the "traditional" switcher window). I did not release the Alt key yet but it crashed. I will report back if the problem shows again.

The crash does not seem to be reproducible.

-- Backtrace:
Application: KWin (kwin), signal: Aborted
