Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-33-generic x86_64
Distribution: Ubuntu 18.04.1 LTS

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

when I try to install a GTK theme from my filesystem, the window just freezes and nothing happens then. I have to manually close it.

The crash can be reproduced every time.

-- Backtrace:
Application: Preferencias del sistema (systemsettings5), signal: Segmentation fault
