Bug#658171: libc6: dns resolving failing after point release update

Package: libc6
Version: 2.11.3-2
Severity: important

The squeeze point release changed libc6's behaviour w.r.t. to name
servers not supporting AAAA queries.

It guess it gets confused if the dns server (in this case a local pdnsd
as the ISP supplied server does not answer to AAAA at all thus causing
long timeouts all the time) replies to AAAA queries with "not implemented".

This causes all name resolution to be quite flawky. wget and apt-get
fail always, while iceweasel fails with each first request, but after
a Ctrl-R that page works.

After downgrading libc6 to 2.11.2-10 it works again.
(Luckily google has that easy to remember resolving dns server that
supports AAAA, so one can actually get the old versions to install
