Application: kdeinit5 (5.13.1)

Qt Version: 5.10.1
Frameworks Version: 5.47.0
Operating System: Linux 4.17.0-12.slh.1-aptosid-amd64 x86_64
Distribution: Debian GNU/Linux testing (buster)

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

closing with "OK" the kcm module after deselecting "spare mappings" (4 mappings set: Italian, Russian, Croatian and Serbian).

I also noticed that after applying some change the process "kcmshell5 [kdeinit5] --args=--tab=layouts kcm_keyboard" didn't exit and prevented opening the kcm module again, therefore I killed it manually.

-- Backtrace:
Application: Modulo delle impostazioni di sistema (kdeinit5), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
