coredump ip6tables

I can not reproduce the issue on demand, but it happens in a CI system that
runs containers, and some of them uses iptables-nft inside of the namespace ,
however, the host system uses iptables-legacy.

iptables segfaults with the following message:

ip6tables[2546654]: segfault at 80 ip 00007fc5c0c65964 sp 00007fff334008b8
error 4 in libnftnl.so.11.2.0[7fc5c0c60000+19000]

attached some of the coredumps I was able to obtain.

Please let me know if I can provide more information.</pre>
