Great find.

If it's easy for you to do, can you install a Tor 0.4.5 deb and see if it
has the same behavior? If yes, then this is a problem with your particular
situation, or a problem with IPv6 that has been there all along. But if
the 0.4.5 deb works and the 0.4.6 deb doesn't, then it is a regression,
perhaps related to the ipv6 changes we did in 0.4.6, and we should try
to track it down.
