Application: systemsettings5 (5.11.90)

Qt Version: 5.9.1
Frameworks Version: 5.42.0
Operating System: Linux 4.13.0-19-generic x86_64
Distribution: Ubuntu 17.10

-- Information about the crash:
- What I was doing when the application crashed:
I run system-settings and when I set some card in system setting it crashed. As i try to run "Input method" in "Regional settings" card, it constantly shows message "Cannot connect to  Fcitx by Dbus, is Fcitx running?".

- Unusual behavior I noticed:
When I use kwin_x11 keyboard in a Polish layout is OK. When I tried to use kwin_wayland, i cannot use polish national letters. That's why i tried to resolve this problem in system-settings. I tried to change it in system-settings, but it seems to be only american english one.

The crash can be reproduced every time.

-- Backtrace:
