Public bug reported:
Binary package hint: kwin
Whenever I close a window with the top-right X, click close on a crash handler
box, use location->quit on konqueror, or many other things, kwin crashes. The
KDE Crash Handler catches it, and provides me with a backtrace. I'm using KDE
3.5.4 and am running XGL with this line in /etc/kde3/kdm/kdmrc:
ServerCmd=/usr/bin/Xgl :0 -fullscreen -ac -accel glx:pbuffer -accel xv:fbo
Here is my Xorg version:
$ Xorg -version
X Window System Version 7.0.0
Release Date: 21 December 2005
X Protocol Version 11, Revision 0, Release 7.0

====================================
By running kwin --replace, I can get back to functioning status again,
until I close another window. Hopefully this problem can be resolved
soon. At least it's giving me a push to start testing out edgy!
