Application: plasma-discover (5.17.80)

Qt Version: 5.13.2
Frameworks Version: 5.65.0
Operating System: Linux 5.0.0-29-generic x86_64
Windowing system: Wayland
Distribution: KDE neon Unstable Edition

-- Information about the crash:
- What I was doing when the application crashed:
Plasma notifies about a Discover crash every time I click on the updates notifier in systray.
However I can open Discover via the apps launcher.

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".
