Application: plasmashell (5.10.90)

Qt Version: 5.9.1
Frameworks Version: 5.37.0
Operating System: Linux 4.10.0-32-generic x86_64
Distribution: KDE neon Developer Edition

-- Information about the crash:
- What I was doing when the application crashed:
Steps to reproduce:
1. Switch main Panel widgets to 'Task Manager'.
2. Click RMB on Panel and choose 'Task Manager Settings...' in context menu.
3. Select any option in menu.


Actual result:
Plasma crashes.


Plasma also crashes after choosing selecting any option in 'On middle-click' dropdown menu in Icon-only Task Manager.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
