Noticed by kepstin on irc:

18:33 < kepstin> ah, that's just not cool. I'm getting an error when editing ACs for tracks on a release,
18:33 < kepstin> Caught exception in MusicBrainz::Server::Controller::ReleaseEditor::Edit->edit "Wide character in subroutine entry at /usr/local/share/perl/5.8.8/JSON/Any.pm line
491"
18:44 < kepstin> trimmed log at http://scs.carleton.ca/~cwalton3/temp/error-track-ac-edit-sanitized.html - Someone remind me to file a bug for this when I have some time this
weekend :/
