 Your log file is not full and there is no error about language file.

Do you mean video duration ? Duration are not retrieved from scraper. 

  
Thank you for your answer!

Yep, sorry, here is the latest: https://pastebin.com/XJBAn2NB
About movie duration: yes, I mean that. Than it seems the time comes from the movie itself. :P But I dont know why all durations are empty. Maybe I missed an option?

Thank you!

Additional info: with stock Estuary (built in) the language pack is working and it display durations too. But I would like to use this one! :)

Update: I reinstalled Kodi and repository.guilouz-1.0.3.zip at first. Nothing more. No movies, no tv shows... Going to language settings and set it to Hungarian. Back to the home screen and voilà! it shutted down. Here is the big log file from the beginnig to the end. :) Skin Helper Service stopped again.

Thank you!

I'm not familiar in Kodi (just started) but    

 Nothing in your log about langage file.   

I have found the problem! :) In the language file (/resources/strings.po) at msgctxt "#13210":

msgid "Started, alarm in {0:d}m" was translated to msgstr "Elindítva, ébresztés {0:s} perc múlva"
but the {0:s} causes problem. Corrected to {0:d} - now everything is perfect. (so far)

Another translation problem, but not causes error: "Régionális" is "Regionális" at #20035.
