           Summary: Plasma Overlay Crash when using Screensaver with
                    plasmoids

        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: panel-devel kde org
        ReportedBy: friesoft gmail com


Version:            (using Devel)
Installed from:    Compiled sources
Compiler:          ++ (SUSE Linux) 4.3.2 20080613 (prerelease) [gcc-4_3-branch revision 136744]

I played around a bit with the plasmoids on screensaver thingy and when I logged back in (from the screensaver (screen locked)) the krashhandler appeared.

Hope I'm not overeager as this is still in heavy development by chani (btw: THX so much for these great oppurtunities you open us up with this))... hm.. that wasn't english.. well I hope you understood it nonetheless ^^
