I have what I think is the same problem. With crossfade enabled, AAC files don't play properly, only small bits of the track play, with lots of stuttering, cracking, blipping, and pausing in between. Unlike in that bug (http://bugzilla.gnome.org/show_bug.cgi?id=436192), this happens at every point in the song, and only happens in AAC files. All of the songs play properly through totem and with crossfade turned off.
