The backtrace is missing important parts. Please have a look at http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports Nevertheless I think we already have that crash report. Is it possible that a window closed while you used alt+tab?
Bug 187761 ? Regards
We still need a proper backtrace and the question isn't answered, so we cannot really fix this crash.
