Comment 1 George Goldberg 2008-06-27 04:44:06 UTC

I can't reproduce this crash using svn trunk r824163 (approx KDE 4.1 beta 2).

Comment 2 Lubos Lunak 2008-07-21 16:23:15 UTC

SVN commit 835987 by lunakl:

Remove emitting of aboutToQuit() from KApplication::xioErrhandler() - the application
is not about to quit, it is about to fall flat on its face. There is really not that
much to do once KDE apps lose their connection to the X server. How that can happen
while the X server still continues to run is a different question and I don't know
the answer. It is quite possible it is caused by careless usage of one X connection
from several threads concurrently without proper locking.
