I'm still seeing the first of these errors after adding official python-3.x support to policyd-spf in Gentoo. We've got,

  * policyd-spf-1.2
  * pyspf-2.0.9
  * pydns-3.0.2
  * python-3.3.x or python-3.4.x

The machine on which I reproduced the error has python-3.3 built with python ipv6 support, but ipv6 disabled in the kernel. Below are the logs for one of the failed transactions.
