Comment:
I've double-checked the failure. It's just a different choice of
generators for the class group ( C250 x C2 for those keeping track)
{{{
sage: i = C(C.number_field().gen(),7)
sage: j = C(C.number_field().gen(),17)
sage: k = C((1/2)*C.number_field().gen() + 137/2,130)
sage: l = C(C.number_field().gen() - 10,41)
sage: i.list()
[0, 1]
sage: j.list()
[125, 1]
sage: k.list()
[1, 0]
sage: l.list()
[88, 1]
sage: l.order()
250
sage: (j*(l^125)).order()
2
}}}
