Please fix this bug! It makes my konqueror crash ~10 times a day and slows down effective work extremely because of lost contents in form fields etc.

Are there any other information you could need for resolving this?

Here's another backtrace of such a crash, looks similar to the one above, but maybe it helps you fixing the problem:

QT update _may_ help, any volunteers to recompile Qt and KDE?
http://www.trolltech.com/developer/notes/changes/changes-3.3.8
- Fixed a rare crash in QPixmap::convertToImage() when XGetImage() fails.

Since I've updated Qt (to 3.3.8) some months ago this never happened again.
So the solution seems to be an upgrade + recompiling affected applications.

I think this bug can be closed.

I'm still on QT 3.3.6, but the crash never occurred again. But it's a rare crash, so....

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.
