Application: plasmashell (5.17.5)

Qt Version: 5.13.2
Frameworks Version: 5.66.0
Operating System: Linux 5.0.0-37-generic x86_64
Distribution: KDE neon User Edition 5.17

-- Information about the crash:
- What I was doing when the application crashed:
I wanted to add a mini program to my top panel. So I browsed through some mini programs and suddenly plasma crashed. It is reproducible.

Maybe interesting:
I installed a few of those in a previous session, but they never showed up in the menu from which you can drag an drop them to the desktop or panel.
By the way - I installed them through the KDE build in interface - not from a downloaded file.

The crash can be reproduced sometimes.

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