I've gotten around trying 1177 now, and the definition of the
relationship does
not break inheritance. But when trying to operate the data-model I
now get:
line 286, in visit_select
orderby = "%s.rowid ASC" % select.froms[0].name
AttributeError: 'JoinMarker' object has no attribute 'name'
which was working as well in 1117. Below the full traceback.

florian -
i have managed to reproduce what is probably the problem youre
having, and made even more modifications to inheritance to more
accurately determine join conditions, relationship directions, and
syncrules. give the trunk a try.
