I have exactly the same problem with 0.5.3. On one machine the mapping
works fine with 0.5.2 on another with 0.5.3 I get the error you
mentioned.

Hierarchies.subscribed_by and back-reference Hierarchies.subscriber are
both of the same direction symbol 'ONETOMANY. Did you mean to set
remote_side on the many-to-one side ?
The related code is:
class Hierarchies(Base, AsDictMixin):
__tablename__ = 'hierarchies'
__table_args__ = ( { 'autoload' : True, })
__mapper_args__ = ({'extension' : HierachiesDeletionLogger()})
id = Column(Integer, Sequence('hierarchies_seq'), primary_key=True)
parent_id = Column(Integer, ForeignKey('hierarchies.id'))
hierarchyshare_id = Column(Integer, ForeignKey('hierarchies.id'))
pos = Column(Integer)
Hierarchies.subscribed_by = relation('Hierarchies',
primaryjoin=Hierarchies.hierarchyshare_id==Hierarchies.id,
backref=backref(subscriber,
remote_side=Hierarchies.hierarchyshare_id),
remote_side=Hierarchies.hierarchyshare_id,
uselist=True,
)
Anything I am missing or something that changed over the last two weeks
at this point?
