#2901: unicode backrefs broken on python 2

 Priority:  medium        |       Milestone:  0.9.xx

--------------------------+-----------------------------------------
 It seems that backrefs can no longer be unicode strings on 0.9 in python
 2. When they are, the following problem occurs, due to the type check `if
 isinstance(self.backref, str):`:

 {{{
   File "...\sqlalchemy\orm\relationships.py", line 1566, in
 _generate_backref
     backref_key, kwargs = self.backref
 ValueError: too many values to unpack
 }}}
