Application: plasma-discover (5.14.5)

Qt Version: 5.11.2
Frameworks Version: 5.54.0
Operating System: Linux 4.15.0-43-generic x86_64
Distribution: KDE neon User Edition 5.14

-- Information about the crash:
- What I was doing when the application crashed: I just opened Discover normally.

- Unusual behavior I noticed: Discover crashes upon opening the app. It doesn't even load, I just get a notification about it crashing.

The crash can be reproduced every time.

-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
