I had a problem with a duplicate album in 1.1.7 (xubuntu), in my case 16 Lovers Lane. After a bit of scanning I found the song list in .config/gmusicbowser/gmbrc.
What I found was that the album_artist_raw was blank but the artist was populated on one of the songs on the album. Once I inserted the artist raw all was well.
6463 1319765179 16 Lovers Lane The Go-Betweens 192...
Versus
6463 1319765179 16 Lovers Lane The Go-Betweens The Go-Betweens 192...
I also notice the filter was as follows
RecentFilters:
- !Filter "album:~:16 Lovers Lane\x00album_artist=The Go-Betweens\x1d"
- !Filter "album:~:16 Lovers Lane\x00\x1d"
Which indicated what to look for.
Thanks
Yes, sorry about that, that is a known bug/mis-feature, an album which has an album_artist for some of its songs, and no album_artist for others will be split into 2 albums.
Currently to put them back together you can simply edit the album_artist tag to make it the same for all of the songs (select the songs->song_properties->fill in the album_artist).
