Bug 223947

*** Bug 236241 has been marked as a duplicate of this bug. ***

Updating bug title.

I can't reproduce this problem and stack trace does not have enough information. If you still see this crash could you please install debug packages for kdebase-workspace and if it happens again post a stack trace?
Thanks.

ok, I'll post the stack trace again.
I have installed kdebase-workspace-dbg.
Cheers
Remy

Ok, so the stack trace from comment #5 seems like a bug 209247. The fix for that was pushed in 4.4 track as Revision 1127913 on May 18. So please try that change or retry with next 4.4 release and see if you still have this crash.

Based on my comment #6 I'll mark it as a dup of 209247 and as fixed in 4.4.4 and 4.5, if you still see it in KDE >= 4.4.4 or 4.5 feel free to reopen it.
