Bug 420828

Application: plasma-discover (5.18.4)

Qt Version: 5.14.2
Frameworks Version: 5.69.0
Operating System: Linux 5.3.0-51-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.18

-- Information about the crash:
- What I was doing when the application crashed:

I tried to open Discover from the app menu to install software.  I had run an update in Discover earlier, it was fine. Just a minute ago, System Settings also crashed on launch, so maybe something larger is happening. I have not yet tried a restart.

The crash can be reproduced every time.

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