Jellyfin client database (on OSMC KODI) keeps malforming

[floris]

After initial setup and partially scanning the Jellyfin server and adding half my series to KODI, my server database corrupted (disk full). I've set up Jellyfin server again, and can perfectly access from other pc web interface without problem, and play movies. Server end works.

The OSMC KODI client successfully connects to Jellyfin server. I cannot however get the KODI client to finish a scan. It does not even want to add libraries, all libraries get set to dynamic. The library scan starts and immediately fails into an error with reference to KODI log. According to kodi log, The client side database on KODI also got corrupted, or "malformed".

I have performed local database reset, and removed jellyfin from kodi, including all setup and other related data, by uninstalling from the menu. Nothing helps. The new install immediately complained about the same issue though. So it seems something lingers on my KODI setup that messes up the database from the start. 

What can I do to get client Jellyfin working again?
