Assertion in clientProcessBody

I've got a user tripping across the following assertion in clientProcessBody (2.7):

        /* Some sanity checks... */
        assert(conn->body.size_left > 0);

conn->body.size_left is 0, and the method is GET; content-length is 226. request_entities is on (obviously).

Any thoughts here? Should this really be >=, or should clientProcessBody never get a 0 size_left?

Cheers,
