Hello everyone!

I recently installed Japanese on my laptop Ubuntu 18.04.4 LTS and now everytime I log in or sometimes even when I use the layout switch combination shortcut, something crashes.

I have 3 layouts, english, greek and japanese at this exact order. If I switch between english and japanese everything works correcty. But if I stwich from greek to japanese, when I type, instead of japanese the computer writes greek characters but with the japanese fonts!!!

Here is a video demonstrating the problem: https://www.youtube.com/watch?v=rLzKI6lN_qM

Here is the error:
