Playlist throws error during scan

[jacobacci]

While diagnosing my last issue, I went through the MinimServer Logs and found a number of issues. Most I have been able to correct.
One that doesn't want to go away, is an error with a playlist. The log says this:

Code:

The playlist looks as follows:

I have checked the paths and they exist. I have pasted the path in the playlist and the path to the file next to each other and they are identical.
\\192.168.0.10\music\2a 44.1_16\Mackerras, Charles\Brahms, Johannes - Sinfonien (44.1_16)\01-01-Symphony No. 1 in C minor, Op. 68_ I. Un poco sostenuto - Allegro.flac

The same playlist plays fine on Logitech Media Server on the same NAS.
My other (relative path) playlists do not throw any errors.

What could be off here?
