Edit Reason: corrected my error in describing the ID3v2 tag placement

There's a lot of nice things to say about Mp3tag (I have a copy myself; even made a financial donation just as I do for moOde). It's great that it can tag FLAC formatted files among many others.
However, the FLAC specification says specifically that FLAC files shall be tagged using a VORBIS COMMENT block only. Mp3tag can read and will populate a VORBIS COMMENT block but *by default* it also appends an ID3V2 tag at the end beginning of the file along with a special marker at the beginning of the file so the file no longer begins with the signature "fLaC" characters and the flac-encoded audio begins after the ID3v2 tag. Some programs can cope with this, some can't. Either way, the result violates the FLAC specification.
When tagging FLAC files with Mp3tag, go to the Tools>Options>Tags>Mpeg and disable writing of ID3v1, IDEv2, and APEv2 tags. Back in the view panel, for FLAC files the Tag column should display FLAC (FLAC). [Full disclosure: I haven't ripped any tracks in more than a year and may be mis-remembering some of these details.]
Can't comment on the original "Library loading fails" issue. I'd have to create a test library to see if mal-tagging is to mal-tagging and I have other things to do ATM.

ETA - I post-edited this message to correct my error in describing where the ID3v2 tag is placed. I was working from memory and mixing up ID3v1 and IDv2.
