Comment:
I applied the patch (no problems) to 4.6.1.alpha2. The thing you observed
does not happen:
{{{
sage: K.<a> = QuadraticField(-14)
sage: S = K.primes_above(2)
sage: S
[Fractional ideal (2, a)]
sage: I = K.ideal(3, a-1)
sage: I._S_ideal_class_log(S)
[1]
sage: I._S_ideal_class_log([])
[1]
}}}
I am now testing...
