SOLVED: Jellyfin crashes when scanning Library

[TheColin21]

Thanks, I was able to get it working.
I suppose you just singled them out because they were the last files listed before the crash?
I continued like this and singled out six files overall that were causing problems. Each an extra from a different BluRay
Some others still threw errors, for example:

Code:

[11:48:41] [INF] [30] MediaBrowser.Providers.MediaInfo.VideoImageProvider: Skipping image extraction due to missing DefaultVideoStreamIndex for /mount/media/Filme/The Grand Budapest Hotel (2014) [imdbid-tt2278388]/extras/The Grand Budapest Hotel_t27.mkv.

I saw this one quite a lot for different files although I don't know why Jellyfin queries any metadata provider at all for extras.

This does not really bother me though as it at least doesn't crash the whole Jellyfin server.
I think there should be some kind of better error handling than restarting the whole server when a scan finds a file that it cannot handle for some reason - especially without obviously alerting the user.
