This works[1] with some problems[2]. But thank you a lot.
I needed a patch[3] to avoid the following error:
But maybe I did something wrong in the API. When you can confirm there
is indeed an issue, I'll start an issue/review.

[1] My setup::
class Artist(ModelSQL, ModelView):
'Artist'
__name__ = 'artist.artist'
name = fields.Char('Name', required=True)
children = fields.Many2Many(
'artist.artist-artist.artist', 'artist_parent',
'artist_child', 'Children', states=STATES,
depends=DEPENDS)
class ArtistArtist(ModelSQL):
'Artist - Artist'
__name__ = 'artist.artist-artist.artist'
_table = 'artist_artist_rel'
artist_parent = fields.Many2One(
'artist.artist', 'Artist Parent', required=True, select=True)
artist_child = fields.Many2One(
'artist.artist', 'Artist Child', required=True, select=True)
XML is the same as in the initial post.
