Comment:
The following works for me in sage-4.6.alpha3, so needs_review as "already
fixed".
{{{
sage: K.<a> = NumberField(x^2 + 23)
sage: G = K.class_group(); G
Class group of order 3 with structure C3 of Number Field in a with
defining polynomial x^2 + 23
sage: (G.0).order()
3
sage: list(G)
[Trivial principal fractional ideal class, Fractional ideal class (2,
1/2*a - 1/2), Fractional ideal class (2, 1/2*a + 1/2)]
}}}
