Description Christian Trippe 2009-05-08 09:39:50 UTC
Version:           Unbekannt (using 4.2.3 (KDE 4.2.3) "release 116", KDE:KDE4:Factory:Desktop / openSUSE_11.1)
Compiler:          gcc
OS:                Linux (i686) release 2.6.27.21-0.1-default

I was using Alt-Tab to switched windows with compositing. I am using the "Kasten mit Minibildern"-Effect (Guessing form the backtrace this is the box switch effect).

I could not reproduce this so far.

Backtrace:

Anwendung: KWin (kwin), Signal SIGSEGV
