Bug 420845

Application: krunner (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:

Just launching Krunner, because Kcalc is not installed.
I also have an issue when launching Discover, I am not sure if it is related, but I cannot send a report for that because the report says it has not enough information despite I have its debug symbols installed.

The crash can be reproduced every time.

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