Comment:
Replying to [comment:2 fwclarke]:
> The root cause of this defect is that the coordinates of class group
elements were Pari integers.
>
> The problem wasn't detected before because only generators were tested
in the doctests for
`sage.rings.number_field.class_group.FractionalIdealClass.order` .
>
> The attached patch fixes the problem and alters one doctest.
Thanks, I will test it. However, you should add a doctest to show that
the problem from this ticket is fixed (so needs_work for this reason).
