Bug 218761

Application: kwin (4.3.80 (KDE 4.3.80 (KDE 4.4 Beta1)) "release 197")
KDE Platform Version: 4.3.80 (KDE 4.3.80 (KDE 4.4 Beta1)) "release 197"
Qt Version: 4.6.0
Operating System: Linux 2.6.31.5-0.1-default i686
Distribution: "openSUSE 11.2 (i586)"

-- Information about the crash:
KWin crashed when showing hidden icons (with compositing enabled), but it does the same when e.g. entering a search command in yast's package manager or just starting/closing an application. First, the desktop lags, then KWin disappears and at last all desktop becomes black and nothing is visible. In some seconds after KWin starts again and works fine until next error. My KWin theme is Nitrogen.

The crash can be reproduced some of the times.

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