Thank you. So the bug is with the test of equality in QQbar, not with
NumberField.
Do you know how to solve this problem with QQbar ?
I tried to look at where is the error, and it

infinite loop:

Hi !
I have a strange bug with NumberField: when I do
sage: pi = x^7 - 2*x^6 + x^3 - 2*x^2 + 2*x - 1
sage: b = pi.roots(ring=QQbar)[3][0]
sage: pi = b.minpoly()
sage: K = NumberField(pi, 'b', embedding=b)
it works well. But if I execute it a second time, then it never terminates!
Do you have a
Hi!
Here are two independent Sage 4.1 sessions which demonstrate that the
construction of NumberField's is context dependent:
sage: K.x = CyclotomicField(5)[]
sage: W.a = NumberField(x^2 + 1)
sage: W
Number Field in a with defining polynomial x^2 + 1 over
