Comment 1 Dario Andres 2009-03-31 14:14:06 UTC
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 :)
Comment 2 Jonas Vejlin 2009-04-01 11:12:57 UTC
I cannot confirm this on debian sid/experimental with kde 4.2.1
Comment 3 Matthias Heinz 2009-04-13 13:00:42 UTC
I can confirm this on debian sid with kde 4.2.2.

@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.
Comment 5 A. Spehr 2009-05-22 16:16:38 UTC
Matthias: did you open a new report and say what you were doing? 


The rest of this can be closed with NEEDSINFO.
