Comment (by malb):
This seems to work now because we avoid Singular
{{{
sage: R.<a,b> = NumberField(x^2-3,'g').extension(x^2-7,'h')[]
sage: h = R.base_ring().gen()
sage: S.<y> = R.fraction_field()[]
sage: xgcd(y^2, a*h*y+b)
(49*a^4*b^2/(343*a^6), 1, ((-1)/(h*a))*y + 49*a^4*b/(343*a^6))
}}}
Carl, any thoughts on this?
