Application: krunner (5.17.5)

Qt Version: 5.14.0
Frameworks Version: 5.66.0
Operating System: Linux 5.4.14-1-default x86_64
Distribution: "openSUSE Tumbleweed"

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

using shortcut alt + f2 and super + space results in opening searching box on the top of the screen (krunner I assume), nothing wrong happens until I start typing, that results in dialog box show up with the message that krunner crashed. As opposite to marked possible duplicate where krunner crashes right away when started.

- Unusual behavior I noticed:

seems to be related that, in my system, many things don't work like alt + f1 and super key not starting application launcher, present all windows as keyboard shortcut and hot corners doesn't work

- Custom settings of the application: 
I don't know if it's related but I installed the fingerprint-gui, in order to finish installing yast proposed to downgrade some packages, from the list of dependencies of that app, as far as I can remember it was at least those two packages which were installed instead of a newer ones:
libQtCore.so.4 () (64bit)
libQtGui.so.4 () (64bit)

The crash can be reproduced every time.

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