avahi does not use ipv6 on 2.4

Description
Using avahi-daemon on kamikaze 8.09.2 (kernel 2.4.35.4, wrt54gl) does not work with ipv6 interfaces.
ipv6 is working on this router and routes ipv6-traffic trough a 6to4 tunnel.
I can access (ssh) the router trough ipv6 too.
logread tells it fails on open a ipv6 socket (full log for restarting avahi-daemon):

I somehow was able to compile avahi-daemon and libavahi from the trunk (0.6.25-1) into a 8.09.2 svn-checkout, but installing it yields the same result.
From reading avahis source, it looks like it is able to actualy create ipv6 sockets, but fails with some option testing.
http://avahi.sourcearchive.com/documentation/0.6.24-1/socket_8c-source.html
As my network is not the default one (all the interfaces have ipv6 addresses in default config, i removed where no ipv4 address is expect for the tunnel interface), i add the output of "ip addr":

Hmm. Can you show us the /etc/avahi/avahi.conf file? On an old-ish build on a Linksys NSLU2, it doesn't seem to complain.
First, the build's uname -a output:
Linux DVB 2.6.32.16 #9 Fri Sep 3 12:01:12 IST 2010 armv5teb GNU/Linux
Then the logread output when the avahi-daemon is restarted with only IPV6 service (I think):

It seems that ipv6 work again in last release of avahi...

Thanks. I just updated and submitted the OpenWrt package to 0.6.30.

Someone can confirm that ipv6 work again?
comment:6 in reply to: ↑ 5 Changed 7 years ago by mikebrady@…
I can just see avahi starting up cleanly with the use-ipv6=yes and the use-ipv4=yes settings, so its behavior seems different to the two reported problems. Don't know anything beyond that. Can the ticket be closed?

More evidence that ipv6 is working on avahi now. I compiled the avahi-utils, set avahi-daemon up in the normal way, except I disabled ipv4 (use-ipv4=no) and enabled ipv6 (use-ipv6=yes), then ran avahi-browse. It reported back some ipv6 services on my local net. Here is part of it:

The same problem seems to exist with Backfire 10.03.1-rc4 avahi-daemon package. If used in IPv6-only mode avahi-daemon stops after the following messages:
