Application: plasmashell (5.13.2)
 (Compiled from sources)
Qt Version: 5.11.1
Frameworks Version: 5.47.0
Operating System: Linux 4.17.0-waltercool x86_64
Distribution: "Gentoo Base System release 2.6"

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

Reproducing the problem is fair easily than using the shortcut to switch between activities. plasma-workspace crashes each time I trigger the control.

Using Qt 5.11.1, Plasma 5.13.2 and Frameworks 5.37.0. Gentoo.

The crash can be reproduced every time.

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