Bug 439121

Application: systemsettings5 (5.22.2)

Qt Version: 5.15.2
Frameworks Version: 5.83.0
Operating System: Linux 5.3.18-59.5-preempt x86_64
Windowing System: X11
Drkonqi Version: 5.22.2
Distribution: "openSUSE Leap 15.3"

-- Information about the crash:
- What I was doing when the application crashed:
I am using the KDE in German therefore I guess it is "info center" what I used was Infozentrum. I was looking for my system and I informed myself about the usb devices. After that I closed the application by clicking on the "x" (top right corner of the window).

- Unusual behavior I noticed:
KDE reported that a crash had happened, but there was not crash that I could observe. I repeated it four times, and always the same behaviour.

The crash can be reproduced every time.

-- Backtrace:
Application: Info Center (systemsettings5), signal: Segmentation fault
