            Bug ID: 353690
           Summary: System Tray plasmoid applet crashes plasma desktop
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: linuxjunkie999 at gmail.com

Application: plasma-desktop (4.11.20)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 3.16.7-24-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
attempt to place the System Tray plasmoid applet into the bottom panel.

- Custom settings of the application:
had to remove the systray to prevent the kde plasma destkop from crashing and
preventing the window manager from fully loading.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Bus error
Using host libthread_db library "/lib64/libthread_db.so.1".
