           Summary: plasma crashes when closing folder view
           Product: plasma
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: panel-devel kde org
        ReportedBy: viesturs.zarins mii lu lv


Version:           kde4daily version from 27th May (using Devel)
Installed from:    Compiled sources

I'm testing the kde4daily inside qemu.
Updated yesterday.

I cannot reproduce this bug,
I guess it might be caused by bad timig.

I fiddled around the border of the default desktop floder view applet, tying to close it, accidently opened the desktop context menu and then finally got hold of the applet's close button. Not sure what state the desktop context menu was in (most probably gone).

Anyway, here is the backtrace:
