           Summary: kwin segfaults when enabling desktop effects
           Product: kwin
           Version: unspecified
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kwin@kde.org
        ReportedBy: sl-bugskde@killefiz.de


Application: kwin (4.3.98 (KDE 4.3.98 (KDE 4.4 RC3)))
KDE Platform Version: 4.3.98 (KDE 4.3.98 (KDE 4.4 RC3))
Qt Version: 4.6.1
Operating System: Linux 2.6.32.8-45.rc2.fc12.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
This is kde 4.3.98 (from the kde-redhat repository) running on Fedora 12 with a
2.6.32.8-45.rc2.fc12.x86_64 kernel.

The crash is reproducible with any 2.6.32-kernel - 2.6.31 Kernels work fine.

The crash occurs as soon as I hit the "Apply"-Button in "Configure desktop
effects"

The crash can be reproduced every time.

 -- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
