This is probably related to bug 180650 If you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? You need to install the "kdelibs5-debuginfo" and "kdebase4-apps-debuginfo" packages Thanks :)
I cannot confirm this on debian sid/experimental with kde 4.2.1

@Matthias Heinz: thanks for the complete backtrace. Could you please report that backtrace in a new report? As this is unrelated with the originally posted backtrace/crash. Also, have you found how to reproduce it ? If you did, please include the steps too.
Matthias: did you open a new report and say what you were doing? The rest of this can be closed with NEEDSINFO.
Marking as duplicate of bug 180650. Thanks *** This bug has been marked as a duplicate of bug 180650 ***
Yes, i did. https://bugs.kde.org/show_bug.cgi?id=190844 We found out this is related to an entry in the kdeglobals file.
