banshee cannot reliably play converted-to-wav files via daap from mt-daapd

I have an mt-daapd server running on Lucid. Rhythmbox is able to detect the server, play songs and use its playlists. While Banshee sees the server and download songlists, it has many problems:
 * sometimes it will not play a song at all
 * if it does play a song, it fails to advance to other songs (once this worked, but then it didn't after)
 * after clicking on a playlist, all playlists then show up twice and are generally unusable
 * sometimes songs show up twice (this is https://bugzilla.gnome.org/show_bug.cgi?id=548366)
 * after the above problems, banshee does not close and has to be killed (Force quit).

With the decision to move away from rhythmbox to banshee, I fear that this will be perceived as a regression.
sometimes will show song duplicates ().

This is the error after trying to advance a song:
