gremlin> g.withComputer().withSack(0).V().hasLabel("person").as("from","to").
......1>            repeat(both().as("to").dedup("from","to").
......2>                   sack(sum).by(constant(1))).

I only noticed the misbehavior in this particular traversal, other tests looked good, so there must be a step that somehow interferes with fold().
