Application: systemsettings5 (5.10.4)

Qt Version: 5.9.1
Frameworks Version: 5.36.0
Operating System: Linux 4.11.9-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
I installed the Qtcurve theme. When I try to open the configuration window by pressing the "configure" button, System Settings srashes. Maybe it's a Qtcurve bug.

The crash can be reproduced every time.

-- Backtrace:
Application: Параметры системы (systemsettings5), signal: Segmentation fault
