By chance I've seen that the function biblio_get_contributor_strings still uses ct_id field, which was replaced by auth_type. Looking for calls to this function I found theme_biblio_tabular. Although it is probably never called here (because the style specific function always exists), it has a quite different interface. Probably you should either fix this function or remove it.
There are some other places where you still use ct_id (in some commented source and in _typeMap() which is not use anymore).

rjerome commentedYes there is still some "experimental" code lurking in there which is not used. I'll get that cleaned up.
