Adding __repr__ to childs object breaks accesss to parent.childs attribute

[Former user]

If we define repr in child object class, then appending it to parent goes silently, but accessing all childs from parent is broken. Test-case is attached

All {{{repr}}} methods in Python must return a string type. Here's the minimal test from the attached:

class ChildWithReprObj(object):
    def __repr__(self):
        print 'Crash the sqlalchemy now! =)'
print repr(ChildWithReprObj())

Change the {{{print}}} to {{{return}}} and you're fine.
