Application: parley (18.12.1)

Qt Version: 5.12.0
Frameworks Version: 5.54.0
Operating System: Linux 4.20.3-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
Just discovered Parley and thought I could try to see what this software was. So, I created a new profile, selected primary and secondary languages, and click on "Start Practicing". As  I didn't know what to do next, I clicked on return to control panel. Then Parley crashes

I repeated the process two times more with the very same result. I don't know if I can help anymore, as I said, it was my very first time using this. I've just updated today Arch linux and my kdeapps are on version 18.12.1

I can try in a few hours with other computer, with arch linux as well, to see if  I can reproduce this also on it.

The crash does not seem to be reproducible.
