Bug 335895

Application: plasma-desktop (4.11.8)
KDE Platform Version: 4.13.1
Qt Version: 4.8.5
Operating System: Linux 3.11.10-11-desktop x86_64
Distribution: "openSUSE 13.1 (Bottle) (x86_64)"

-- Information about the crash:
I selected Milou and added it to systray. Today when I booted to the desktop, the plasma-desktop crashed. The only way around this is to log in to console and manually remove the entry from the systray.

The crash can be reproduced every time.

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