Thanks for the report!
- If you can reproduce the crash at will (or you experience this regularly), can you install the "kdebase-workspace-dbg", "kdelibs5-dbg" packages and post a complete backtrace here? (you can get more information at http://techbase.kde.org/User:DarioAndres/Basic_Guide_about_Crash_Reporting ) Thanks

Comment 2 Aaron J. Seigo 2010-05-26 04:25:56 UTC

waiting for full backtrace (still)

Comment 3 Myriam Schweingruber 2012-05-28 22:26:48 UTC

Closing for lack of feedback.
