For the record: my collision is not contrived. It came up in actual code where I was hashing some custom class using tuples and found an unexpected high number of collisions, which I eventually traced back to the collision I reported here.
By the way, I think the worst real-life hash collision is
>>> hash(-1) == hash(-2)
True
