It seems that a FLAC tag containing " - " is split in two parts and added twice to the file. For example, I had a file whose title appeared as "[D568] - I. Allegro moderato" in EasyTag, but the FLAC file contained:

GStreamer encoded vorbiscomment^P^@^@^@^L^@^@^@TITLE=[D568]^Y^@^@^@TITLE=I.

EasyTag is able to read and concatenate the two parts to show them correctly, but other software (like GStreamer-based apps) only see the first part. Needless to say, this small detail was driving me mad...


(I really appreciate that you take up maintainership of this otherwise very powerful app!)
