 I was playing around with 2.6 and from __future__ import unicode_literals
 and discovered that if the value of the backref argument to mapper
 is a unicode string, mapper fails with:

     AttributeError: 'unicode' object has no attribute 'get_extension'

 A test case is attached.  The failure can be replicated either as
 is (passing u'Author' as the backref) or by uncommenting the
 future import.
