Hi there, If you use stretch to keysinging like me, you may also had the difficulties to sign some ECC keys getting from this debconf. I already reported the issue as https://bugs.debian.org/906545
Since this issue doesn't occur on unstable version, I uploaded the stretch-backports version in DELAYED/3 [1]. It also need to get through NEW queue [2]. So I guess you will be able to install the fixed gnupg from stretch-backports in 10 days.
