Description David 2016-01-24 18:08:14 UTC 
Application: plasmashell (5.5.3)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-1-default x86_64
Distribution: "openSUSE Tumbleweed (20160117) (x86_64)"

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

- Unusual behavior I noticed:
Second screen cannot be set as the main screen without losing widgets.  Widgets dissappear when switching main screens, widgets reappear when disconnecting the second screen and going back to the laptop screen.  Repeating the process eventually results in plasma crashing completely.

The crash can be reproduced sometimes.

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