Description Brian 2016-08-01 16:14:00 UTC 
Application: plasmashell (5.7.1)

Qt Version: 5.6.1
Frameworks Version: 5.24.0
Operating System: Linux 4.6.4-301.fc24.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

Dragging desktop widget to secondary monitor causes Plasma to crash. Only happens every few times when moving the widgets and seems to happen with all widget types I have tried.

- Unusual behavior I noticed:

Upon crash desktop reverts to a "generic" background and loses my wallpaper config.

The crash can be reproduced sometimes.

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