Bug 425481

Application: krunner (5.19.4)

Qt Version: 5.14.2
Frameworks Version: 5.72.0
Operating System: Linux 5.4.0-42-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.19

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

Type Alt-F2
Now start typing the command like kpat

After typing the first character and before any character is shown in the krunner applet it crashs.

The crash can be reproduced every time.

-- Backtrace:
Application: krunner (krunner), signal: Bus error
