Description
The following does not work
sage: K.<t> = NumberField(x^5-9*x^4+22*x-71) sage: v = K.ideal(2, t^3 - 8*t^2 - 7*t - 3) sage: c = K.class_group()(v) sage: c.order()
giving a type-error. While it should give back 3.

The problem was sorted out in #11234, which was merged in sage-4.7.1.alpha0. So I think this ticket can be closed as a duplicate.
