           Summary: Plasma-Desktop crashes, when adding a second system
                    tray and disabling options of that tray
           Product: plasma
           Version: unspecified
          Platform: Archlinux Packages
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: plasma-bugs@kde.org
        ReportedBy: pano_90@gmx.net


Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.3
Operating System: Linux 2.6.38-ck x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

I have two pannels. On one there is a fully set up system tray, with the
notifications option disabled, for some reasons unrelated to this bug.
I have a second panel, where I then added a second system tray. When I then
open up the settings dialog of that second systray and deselect everything
except the notifications option, and press apply, plasma-desktop will crash.

The crash can be reproduced every time.
