Description pearcebrad 2015-12-01 02:58:42 UTC 
Application: plasmashell (5.4.2)

Qt Version: 5.5.0
Operating System: Linux 4.1.12-1-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
A television attached via HDMI as a second monitor had just been turned off.
- Unusual behavior I noticed:
The main desktop background regularly changes to the second monitor background, especially following a suspend caused by the screen closing. Full windows regularly go under the bottom task bar, though they work when the computer is first turned on. The entire system of plasma stops working with regularity. 
- Custom settings of the application:
television hooked up to computer via HDMI, television is regularly used on a differetnt input setting.

The crash can be reproduced sometimes.

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