Bug#801087: nft utility from nftables segfaults

[Pyotr Son]

Package: nftables
Version: 0.5-1~bpo8+1

This is jessie with jessie-backports enabled and kernel 
4.1.0-0.bpo.2-amd64 installed from backports as well.
libc version 2.19-18+deb8u1.
nft started to segfault right after update to 0.5:

(ruleset is empty)
# nft -f /etc/nftables.conf
Segmentation fault

Contents of nftables.conf:

#!/usr/sbin/nft -f

flush ruleset
