[ipset] possible bug handling multi-resolved FQDNs

Hi there,
I found this:

root@pica:~# ipset create repos_ipv6 hash:ip family inet6
root@pica:~# ipset add repos_ipv6 wildcart.fedoraproject.org
ipset v6.12.1: Syntax error: cannot resolve 'wildcart.fedoraproject.org' 
to an IPv6 address: Name or service not known
Syntax error: cannot parse wildcart.fedoraproject.org: resolving to IPv6 
address failed
root@pica:~# dig +short wildcard.fedoraproject.org AAAA
2001:4178:2:1269::fed2
2607:f188::dead:beef:cafe:fed1
2610:28:3090:3001:dead:beef:cafe:fed4

The IPset package is the Debian Wheezy one:
Package: ipset
Version: 6.12.1-1

Kernel: Linux 3.2.0-2-686-pae (SMP w/4 CPU cores)
Architecture: i386 (i686)


In a machine with the same version of the package but amd64 the 
bug/error doesn't exist.

Any idea?

Best regards

When you write "wild cart", I have to think of the movie
poster of Jackass (The Movie).
So yeah, so much for cards vs carts.
