           Summary: KWin crashed after closing a window group and dragging
                    a window
           Product: kwin
           Version: unspecified
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kwin@kde.org
        ReportedBy: matt@cfxnetworks.com


Application: kwin (4.4.3 (KDE 4.4.3))
KDE Platform Version: 4.4.3 (KDE 4.4.3)
Qt Version: 4.6.2
Operating System: Linux 2.6.31.12-0.2-default i686
Distribution: "openSUSE 11.2 (i586)"

-- Information about the crash:
I'm not entirely sure what caused the crash, but I closed a window group and
then stared draging a window from the panel and KWin crashed. Perhaps the
backtrace is more useful?

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