Application: plasma-discover (5.12.8)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 5.3.0-51-generic x86_64
Distribution: Ubuntu 18.04.4 LTS

-- Information about the crash:
- What I was doing when the application crashed: first time clicked on update icon. Second time from restart application. Third through fifth time from application launcher (Discover).

- Unusual behavior I noticed:
before crashing Discover couldn't see the flatpack repository.

The crash can be reproduced every time.

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