Application: krunner (5.12.1)

Qt Version: 5.10.1
Frameworks Version: 5.43.0
Operating System: Linux 4.15.3-2-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
Entered "kipi". After a couple of seconds krunner just krashed.

- Custom settings of the application:
I have Firefox as main browser. Thought it may worth mentioning besause i have error like that on console, when krunner strted manually and crashes:
QSqlDatabasePrivate::removeDatabase: connection '/home/<...>places.sqlite' is still in use, all queries will cease to work.

Also the issue is repeating on my home PC with NVIDIA, and I've never seen that on my work PC with Intel graphics. These are two completely different systems hardware-wise, but have mostly the same software. And on my home PC KDE seems to be mush less stable, I believe that it is GPU-related issue after all.

The crash can be reproduced every time.

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