Application: kwin (4.4.3 (KDE 4.4.3))
KDE Platform Version: 4.4.3 (KDE 4.4.3)
Qt Version: 4.6.2
Operating System: Linux 2.6.33.7-server-2mnb i686
Distribution: "Mandriva Linux 2010.1"

-- Information about the crash:
Kwin crashes when system restores opened windows/applications from the last session.
Maybe that's why some documents in the taskbar (i.e txt documents opened in Kwrite) aren't grouped.

This problem appeared after changing my wallpaper from default to a picture (I'm using Mandriva 2010.1).

The crash can be reproduced every time.
