Application: plasmashell (5.17.4)

Qt Version: 5.13.2
Frameworks Version: 5.65.0
Operating System: Linux 5.0.0-37-generic x86_64
Distribution: KDE neon User Edition 5.17

-- Information about the crash:
- Unusual behavior I noticed:
When right clicking an application in the "start" applications menu, plasma crashed. I tried it again when it reapeared and it also crashed again, and now it completely disapeared. Everything works still that is open, but bottom panel is gone.

The crash can be reproduced every time.

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