Comment:

 This broke one of our favorite things in the world: attachment taxonomies.

 An attachment taxonomy can be register not just to 'attachment', but to a
 particular mime type, like `attachment:image` or `attachment:video`.

 get_object_taxonomies() handles this, but only if it is passed a post
 object. At this stage in querying, we're obviously too early for that. So,
 when we come across the 'attachment' post type and do
 get_object_taxonomies( 'attachment' ), we don't get back any of the mime-
 type-specific taxonomies, and that causes us to avoid including
 'attachment' in the query.

 There *are* some potential fixes for this. Basically, we need an API that
 says "get me all attachment taxonomies", essentially looking for any
 object type that is either 'attachment' or starts with 'attachment:'.

 I'm at the point where we revert this for 3.5 and revisit it later.
