Transmission does not connect to ipv6 trackers

[Ambricka]

Binary package hint: transmission

Trying to download some ubuntu isos from ipv6.torrent.ubuntu.com
They add nicely in transmission
However, transmission never asks the tracker for any peers.
tcpdump/wireshark show no traffic to the tracker address

$ apt-cache policy transmission-gtk

Description: Ubuntu jaunty (development branch)
Release: 9.04

Transmission 1.5x will only resolve IPv4 addresses due to some things that need to be reworked internally.

See the Transmission ticket here: http://trac.transmissionbt.com/ticket/1731

I've confirmed this bug. Some sort of fix went into 1.60-1 debian release but I'm skeptic about it and have to check it out with Transmission Developer. If this fix is causing problems described in upstream bts bug linked to this bug report I'll ask debian maintainer to revert this patch.
There is still no right solution of this problem as far as I know.

This may have been fixed in Transmission 2.20: https://trac.transmissionbt.com/wiki/Changes#version-2.20
"Better support for IPv6-only trackers"

Can anyone confirm? Transmission 2.33 is in oneiric.

I downlaod Ubuntu 12.04 ISO and the ipv6 trackers is red.
