This is likely to be bug 210146. - 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

The backtrace seems to be a bit different (bug 223991). But in any case, both issues are Qt4.6.0 bugs, fixed in 4.6.1 Regards *** This bug has been marked as a duplicate of bug 223991 ***
