           Summary: crash  (assert) on desktop change, apparently in
                    KWinInternal::Client::plainResize
           Product: kwin
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kwin kde org
        ReportedBy: a8603365 unet univie ac at


Version:            (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc (GCC) 3.3.1 (SuSE Linux) 
OS:          Linux

When switching from desktop 1 to desktop 4 (running kuickshow in fullscreen mode and \
on all desktops amarok), kwin aborted with the below bt. After restarting kwin, there \
were only two (instead of my normal 7) desktops available, the window style was \
switched to keramik (normally ModernSystem). I restarted the X server (maybe kdesktop \
would have been enough?!) and now the selection text color was suddenly black \
(normally white). All very annoying, but this very report is about the kwin crash.   \
:-)

> From gdb:
Program terminated with signal 6, Aborted.

I have one tiny local change in geometry.cpp that doesn't seem to be related. So feel \
free to dismiss the bug report.  :-/ _______________________________________________
