Comment (by DayneSorvisto):
Looking at the source in rings.arith.py it seems that the problem is this
line which generates a probably prime.
{{{
smallest_prime = ZZ(lbound-1).next_probable_prime()
}}}
perhaps there could be some more error checking for large numbers so Sage
doesn't return obviously composite numbers?
