When playing all songs from an album, any tracks with the same artist and composer appear twice in the playlist.  This only occurs when the album has been reached via Browse -> Artists etc, and not via Browse -> Albums.

The SQL statement executed (from --d_sql) was:

2006-07-06 13:25:57.1034 SELECT me.id, me.url, me.content_type, me.title, me.titlesort, me.titlesearch, me.album, me.tracknum, me.timestamp, me.filesize, me.tag, me.disc, me.thumb, me.remote, me.audio, me.audio_size, me.audio_offset, me.year, me.secs, me.cover, me.vbr_scale, me.bitrate, me.samplerate, me.samplesize, me.channels, me.block_alignment, me.endian, me.bpm, me.tagversion, me.drm, me.moodlogic_id, me.moodlogic_mixable, me.musicmagic_mixable, me.musicbrainz_id, me.playcount, me.lastplayed, me.lossless, me.lyrics, me.rating, me.replay_gain, me.replay_peak FROM tracks me  JOIN albums album ON ( album.id = me.album ) LEFT JOIN contributor_track contributorTracks ON ( contributorTracks.track = me.id )  JOIN contributors contributor ON ( contributor.id = contributorTracks.contributor ) WHERE ( album.id = ? AND contributor.id = ? ) ORDER BY album.titlesort, me.disc, me.tracknum, me.titlesort (`57', `231')

Perhaps this should be a SELECT DISTINCT instead.
