-- Information about the crash:
- What I was doing when the application crashed:
Under wayland session, I opened kinfocenter -> Graphical Information -> X-Server, and kinfocenter crashed, this happens everytime on multiple configurations (openSUSE Tumbleweed with 5.8.5 and latest git packages, I also remember seeing this on Fedora and Neon

The crash can be reproduced every time.

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