next(iter(S.Integers*S.Integers)) hangs (expected (0, 0), ...)

[smichr]

While having finite and infinite set does not cause problems, having only two does

>>> next(iter(Range(3,5)*Range(1,3)))
(3, 1)
>>> next(iter(Range(3,5)*S.Integers))
(3, 0)
>>> next(iter(Range(3,5)*S.Integers*S.Integers))
(3, 0, 0)
>>> next(iter(S.Integers*S.Integers))
...hangs

All the examples with Integers hang now.
