I've found the "fix". The package in Karmic uses the deprecated libmusicbrainz version 2 instead of 3 (the package of libmusicbrainz 2 is called libmusicbrainz4 in Ubuntu).
Jaunty switched from version 2 to 3, which introduced this bug. Now Karmic switched back, which "solves" this bug again. I've opened another bug report #455461, which explains why this is even worse than before. -- sound-juicer tags mp3 files with incorrect musicbrainz ids https://bugs.launchpad.net/bugs/353389 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
