Description
this was reported to me by Emmanuel Thome with Sage 3.0.3:
sage: R=Integers(17^5) sage: R Ring of integers modulo 1419857 sage: R(17)^5 1419857 sage: R(17)^5==0 False sage: R(R(17)^5) 0
Clearly R(17)^{5 is not in canonical form, which is what we would expect... However: }
sage: R(17)*R(17)*R(17)*R(17)*R(17) 0

Hi Paul,
David Harvey reported the same problem from sage-devel and already put up a patch that has been positively reviewed patch at #3747. So I am closing this as a duplicate.
Cheers,
Michael
