Description Stefan Usenbinz 2008-11-09 22:46:18 UTC
Version:            (using Devel)
Compiler:          gcc-Version 4.2.4 (Ubuntu 4.2.4-1ubuntu3) 
Installed from:    Compiled sources

Well, from the backtrace this rather looks like a Qt problem than a KWin problem, but since KWin was blamed for the abort...
This crash occured after the upgrade of qt-copy to SVN revision 882016 and applying the latest patches. So it might well be that the problem has been introduced with qt-copy.
KDE SVN revision is 882094.

Haven't seen any crashes on logout for a while. Currently on rev 899204 (qt-copy 899143). Closing.
