 While working on 6177, I've discovered that when auth_type is
 REND_NO_AUTH, rend_client_send_introduction() leaves auth_len
 uninitialized.  This worked with the old INTRODUCE2 parsing code in
 rend_service_introduce(), but doesn't match the spec and broke with my
 initial rewrite of the parser.  I'll make sure my new
 rend_service_introduce() handles this behavior, but it should still get
 fixed - it should be a pretty quick fix.
