Application: plasmashell (5.14.2)

Qt Version: 5.11.2
Frameworks Version: 5.51.0
Operating System: Linux 4.18.16-zen1-1-zen x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I was toying with plasma-pa because I realised that popup menu doesn't close when applet loses focus.

- Unusual behavior I noticed:

Popup menu in plasma-pa was sticky.

plasma-workspace recompiled to contain debugging symbols

The crash can be reproduced every time.

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