Bug Description

I am trying to use SoundConverter to convert FLAC to MP3 with all the tags. Many of the tags are OK but there are the following issues:

1. the tag "musicbrainz discid" is created (this tag is the same as the official tag musicbrainz_discid but the underscore is replaced with a space).
2. the values for the tags musicbrainz_albumartistid, musicbrainz_albumid and musicbrainz_artistid have been duplicated.
3. some MusicBrainz tags () have but converted to comments.

In Original FLAC
totaldiscs = 1
musicbrainz_albumartistid = efef848b-63e4-4323-8ef7-69a48fbdd51d
musicbrainz_albumid = da93145a-1dab-4035-ace2-5afad1b89cd5
musicbrainz_artistid = efef848b-63e4-4323-8ef7-69a48fbdd51d
musicbrainz_discid = hSLro2usS2lpVlDV2sVdApb4rY0-
musicbrainz_trackid = 4a6d33ac-9407-4686-bf53-fd5aee08fa08

In the output MP3
comment:totaldiscs = 1
musicbrainz discid = hSLro2usS2lpVlDV2sVdApb4rY0-
musicbrainz_albumartistid = efef848b-63e4-4323-8ef7-69a48fbdd51d; efef848b-63e4-4323-8ef7-69a48fbdd51d
musicbrainz_albumid = da93145a-1dab-4035-ace2-5afad1b89cd5; da93145a-1dab-4035-ace2-5afad1b89cd5
musicbrainz_artistid = efef848b-63e4-4323-8ef7-69a48fbdd51d; efef848b-63e4-4323-8ef7-69a48fbdd51d
musicbrainz_discid = hSLro2usS2lpVlDV2sVdApb4rY0-
musicbrainz_trackid = 4a6d33ac-9407-4686-bf53-fd5aee08fa08

If I remove the duplicate from Id from musicbrainz_albumid then I can use Picard (a MusicBrainz tagger) to place all the tags back into the MP3 file again so the tags are supported in MP3.

Version:
  SoundConverter 1.5.4 & 2.1.1
  gstreamer 0.10.19
  OpenSuSE 12.3

Test a FLAC --> OGG conversion and that looks fine.

Description:

Note the duplicated 'MusicBrainz Artist Id' vs. 'musicbrainz_artistid' and 'MusicBrainz Album Id' vs. 'musicbrainz_albumid'.

Picard apparently merges those into one tag, with ';' separating the two values

I keep my music in FLAC on an external drive, and convert to MP3 for my devices.

A lot of the MusicBrainz tags get corrupted in the conversion process, like what other commenters said above; opening the files with Picard then adds extra tags all over again.
