squid-deb-proxy problem on Raring, IPv6 I think.

[Colin Law]

I have a problem with squid-deb-proxy on Raring which I think may be
an IPv6 related issue.  I hope someone can tell me whether it is a bug
or a configuration issue.  In fact even if it is configuration it is
likely also a bug as I am seeing it on a virgin install.

With squid-deb-proxy and squid-deb-proxy-client on the same machine,
running Raring, when I run apt-get update I see error messages for
every connection, for example

W: Failed to fetch
http://gb.archive.ubuntu.com/ubuntu/dists/raring-updates/restricted/binary-i386/Packages
 Cannot initiate the connection to fe80::290:f5ff:fece:342f:8000
(fe80::290:f5ff:fece:342f). - connect (22: Invalid argument)

I think it is actually the client that is the issue as when I run
squid-deb-proxy-client on another box, running 12.04, but using the
proxy on Raring, then all is well.

Any suggestions greatly appreciated.
