I've seen this bug before and the debugging information is unfortunately
not that useful in this case. If you could reproduce this when running
kwd in valgrind, that might be more useful.

Use something like:

valgrind --tool=memcheck kde-window-decorator 

in case you haven't used valgrind before..

[compiz] KWD Maximize bug and crash

[Diogo Ferreira]

Hi, KWD is crashing regularly here when closing a window (especially 
mplayer), I've attached the debugging information.


Also, there's this bug when windows are maximized, in some themes the 
decoration is drawn incorrectly, sometimes it's not drawn at all, I'm 
not sure if it's a known bug.
