The "translation=True" flag does not work after upgrading to sage 3.2.3
I am not sure when this behaviour was introduced. In version 2.10.2 it
works fine, unfortunately I don't have a more recent old sage to check.
sage: foo = Graph()
sage: foo.add_edges([(0,1,1),(1,2,2), (2,3,3)])
sage: foo.automorphism_group(translation=True)
