Comment 1 Dario Andres 2010-01-27 17:15:50 UTC

- If you can reproduce the crash at will (or you experience this regularly), can you install the "libqt4-dbg" package and post a complete backtrace here? (you can get more information at http://techbase.kde.org/User:DarioAndres/Basic_Guide_about_Crash_Reporting ) Thanks
(This could be bug 210146)
