Lib refresh fails, very manual work to corret

[guerda]

I regularly import new media into my music collection. My issue is that the refresh fails all the time and does not complete. The error is always similar like below, but I cannot make out what is meant with that. 

I cannot search for an album  52976ba7090ba7d0c24f2676eaf529c5 in Jellyfin UI, but have to manipulate a URL to display the album. If I then remove this album, the refresh can be started again and it continues, but not very far.
Any idea how to solve this more once and for all?

It would be great if the error message would be more helpful to solve this problem, too.

Code:

Are you running 10.9?

I am running 10.8.13 via Docker.

This user triggered this issue by having duplicate folders that, somehow, had the exact same name in the same folder. I'm also wondering if having duplicate folders, even if not in the same place, could trigger this.

There's also this issue that we are tracking.
