Application: plasmashell (5.8.9)

Qt Version: 5.6.1
Frameworks Version: 5.36.0
Operating System: Linux 4.13.0-43-generic x86_64
Distribution: Ubuntu 16.04.4 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Dragging plasmoid/widget "CPU Load Monitor" or "Network Monitor" from one monitor to another. Both of these crash plasmashell when dragged from one monitor to another.

However, the "System Load Viewer" can be dragged from one monitor to another with no problems.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
