Application: systemsettings5 (5.9.5)

Qt Version: 5.7.1
Frameworks Version: 5.33.0
Operating System: Linux 4.10.15-200.fc25.x86_64 x86_64
Distribution: "Fedora release 25 (Twenty Five)"

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

I was previewing the window switcher for a **second time** when the configuration app crashed. It can be reproduced by relaunching the settings app and doing the same thing again.

The crash can be reproduced every time.

-- Backtrace:
Application: Configuration du système (systemsettings5), signal: Segmentation fault
