           Summary: plasma desktop crashes after unfolding yakuake console
           Product: plasma
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: plasma-bugs@kde.org
        ReportedBy: nightowl@inorbit.com


Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-18-generic i686
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
After I have updated from KDE 4.4.1 to 4.4.2 the plasma desktop crashes when I
unfold the yakuake console. In most cases it recovers but it may also happen
that the screen remains black. In case that matters: plasma theme is Air for
Netbooks, widgets on the desktop are folderview, customizable weather, activity
bar and daisy.

The crash can be reproduced every time.

 -- Backtrace:
Application: Plasma-Arbeitsfläche (kdeinit4), signal: Segmentation fault
