Description Hynek Vychodil 2015-12-07 15:18:37 UTC 
Application: plasmashell (5.4.2)

Qt Version: 5.5.1
Operating System: Linux 4.2.0-1-amd64 x86_64
Distribution: Debian GNU/Linux testing (stretch)

-- Information about the crash:
- What I was doing when the application crashed:
Plug in secondary monitor
- Unusual behavior I noticed:
Panels appear at secondary monitor even it is not set as primary output
- Custom settings of the application:
I have two panles to the left and bottom and I set secondary monitor to the left of primary one.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
