[NB This is a different bug from the one on #5153]
Chris Wuthrich reports:
{{{
sage: K.<w> = NumberField(x^2-x-232)
sage: E = EllipticCurve([2-w,18+3*w,209+9*w,2581+175*w,852-55*w])
sage: E.local_data()
[]
sage: E.simon_two_descent(verbose=2)
booom.
}}}
The same example runs fine in gp using the same version of the script
ell.gp that Sage has (in version 4.4.4) and the same version of gp.
