           Summary: crashed when changing multimedia backend
           Product: kdelibs
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: knotify
        AssignedTo: ogoffart@kde.org
        ReportedBy: greg.martyn@gmail.com


Application that crashed: knotify4
Version of the application: 4.0
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.29.6-217.2.16.fc11.x86_64 x86_64
Distribution: "Fedora release 11 (Leonidas)"

What I was doing when the application crashed:
I changed the multimedia backend from gstreamer to xine in system settings,
then hit apply. Dragon player and knotify immediately crashed.
