Bug 423891

Application: krunner (5.19.80)

Qt Version: 5.14.2
Frameworks Version: 5.72.0
Operating System: Linux 5.3.0-62-generic x86_64
Windowing system: X11
Distribution: KDE neon Unstable Edition

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

I opened KDE Neon Developer's Edition on a virtual machine to check another issue with krunner, and tried to invoke it by typing on the desktop and it crashed.  I tried it several times and got the same result each time.

The crash can be reproduced every time.

-- Backtrace:
Application: krunner (krunner), signal: Segmentation fault
