Bug 388443

Application: systemsettings5 (5.5.5)
 (Compiled from sources)
Qt Version: 5.5.1
Operating System: Linux 4.10.0-42-generic x86_64
Distribution: Ubuntu 16.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I have several problems with system settings

- Custom settings of the application:
Custom Shortcuts are not enabled by default on login.
only when i check in the check box it works (i.e ctrl+alt+t for terminal),
and the Apply button is not active so i can't save checked option Start the Input Actions daemon on login, so every time i log in i have to turn it on

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
