For reproducing just try to use Kopete IM client and try to connect to some jabber server. Kopete must use IPv6 recursive DNS server for translating jabber SRV or A records. DNS server address is read from standard file /etc/resolv.conf.

So if you do not have IPv6 connectivity, you can you start some recursive (or forward) DNS server on IPv6 localhost and set nameserver ::1 in /etc/resolv.conf. This is quick hack, but should work.

I see that NetworkManager on Ubuntu is already using dnsmasq (as forwarder), but does not have enabled IPv6 support on localhost. It automatically add "nameserver" line into /etc/resolv.conf.

To tell dnsmasq to listen also on IPv6 localhost add configuration like:
$ echo listen-address=::1 > /etc/NetworkManager/dnsmasq.d/ipv6
(and reboot)

And set "nameserver ::1" in /etc/resolv.conf (note that NetworkManager is changing that file when reconnecting...)
