same issue, but on FreeBSD 11.1 (uname -K: 1101001 & -a: FreeBSD container-host1 11.1-RELEASE FreeBSD 11.1-RELEASE #0 r321309: Fri Jul 21 02:08:28 UTC 2017 [email protected]:/usr/obj/usr/src/sys/GENERIC amd64 )

This was fixed in truenas/py-libzfs#1 - I'm confused about the upstream repo situation, but would suggest to cherry-pick that commit.
