Description
When not working with regular crystals, one gets an infinite recursion when calling phi:
sage: B = CrystalOfTableaux(['A',2], shape=[2,1]) sage: La = RootSystem(['A',2]).ambient_space().fundamental_weights() sage: T = TensorProductOfCrystals(TCrystal(['A',2], La[1]+La[2]), B) sage: t = T.an_element() sage: t.phi(1)

We weren't iterating over the correct values for calling _sig().
