Description Marcelo Ricardo Leitner 2015-04-23 17:07:39 UTC 
Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 4.0.0-0.rc5.git4.1.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
- What I was doing when the application crashed:
Disabling laptop screen. I was trying to fix the taskbar being displayed on the wrong monitor as a result of the other bug (I will get the number in a few), but then it crashed.

- Unusual behavior I noticed:
Crashed, instead of disabling the screen and putting the taskbar on the other screen.

- Custom settings of the application:
F22 updated, dual head, laptop screen and DP.

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