Application: systemsettings5 (5.8.2)

Qt Version: 5.7.1
Frameworks Version: 5.27.0
Operating System: Linux 4.8.0-2-686-pae i686
Distribution: Debian GNU/Linux testing (stretch)

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

Selected 'Breeze' theme in 'Application Style' list of available themes for windows.
Clicked 'Apply' and closed the window, when the crash error message appears.
There's no error I can see, though, because the style changes correctly.

The crash can be reproduced every time.

-- Backtrace:
Application: Impostazioni di sistema (systemsettings5), signal: Aborted
