Bug 359419

Application: plasmashell (5.5.3)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-3-default x86_64
Distribution: "openSUSE Tumbleweed (20160117) (x86_64)"

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

I logged in and tried to connect to VPN. I have external monitor, connected via docking station - it might be related, as the crash happens also when I re-connect my laptop to the docking station and click in the tray area.

The crash can be reproduced sometimes.

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