Bad dns handling when server has both AAAA and CNAME

[Lionel Dricot]

Using Polipo + Privoxy on Intrepid as "howtoed" here :
https://help.ubuntu.com/community/DnsmasqPolipoPrivoxy
But without dnsmasq because we already have an internal DNS server.

It appears that sometimes, polipo takes a very long time to reply to a request. One example : go to google images (with a fresh polipo installation) and search for whatever you want. It happens that thumbnails will not load before one or two minutes

The polipo.log file tells you that :
Host tbn0.google.com has both AAAA and CNAME -- ignoring CNAME.

But instead of ignoring CNAME, it seems to have a timeout, which is really similar to this 3 years old bug :

This isn't a bug, simply disable ipv6 dns lookups.

Actually, it is a bug: http://<email address hidden>/msg00577.html

Disabling IPv6 lookups is not a fix.

Upstream has comitted this patch, can the deb be updated to include it?
