Description kkolle 2016-08-10 14:04:26 UTC 
Application: plasmashell (5.7.2)

Qt Version: 5.6.1
Frameworks Version: 5.24.0
Operating System: Linux 4.6.5-200.fc23.x86_64 x86_64
Distribution: "Fedora release 23 (Twenty Three)"

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

As at most boots the secondary display - the laptop screen - does not show gadgets and background. Then I in the system settings switch the monito off and back on. This causes the crash and after the restart everything is fine and back in order.

The crash can be reproduced every time.

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