14472 some elliptic curve functions over number fields fail over relative fields John Cremona John Cremona "This was reported by Alejandro Argaez:
{{{
sage: K1.=NumberField(x^2+x+1)
sage: m=polygen(K1)
sage: K2.=K1.extension(m^2-w+1)
sage: E=EllipticCurve([0*v,-432])
sage: E.global_minimal_model()
}}}
The error is that the degree() function is called on the ring of integers of a relative number field.
In fixing this bug (which should be easy) it would be a good idea to add relative examples to as many functions as possible in {{{ell_numberfield.py}}}
