Description Marc de Bruijn 2009-02-09 10:51:52 UTC
Version:           4.2.00 (using KDE 4.2.0)
OS:                Linux
Installed from:    Debian testing/unstable Packages

When a window is closed and I attempt to switch applications while that process is handled Kwin crashes

I have this primarily with GTK applications (Synaptic opens and closes windows automatically when updating or installing, for example), but it's possible it happens with Qt ones as well. GTK applications are a bit slower, while Qt ones close nearly instantaneous, which might explain why I have this problem only with GTK applications.

Kwin respawns after crashing, which is quite nice, considering opening and closing windows can happen a lot during a session.

I got this backtrace (it's... err... rather short):

Application: KWin (kwin), signal SIGSEGV

I think that this is a duplicate of bug #179865. But to be sure: are you using desktop effects and an effect for alt+tab? Boxswitch or coverswitch?
Comment 2 Marc de Bruijn 2009-02-09 11:33:11 UTC
It could be. I'm using desktop effects and Box switch for Alt+Tab.
