The patch apply in bug #205281 causes avahi-daemon to not start for me (and presumably others). I put attachments on that bug showing output of /var/log/all.log and rcorder output with and without the 'BEFORE' line patched in that bug. I build my own packages with Poudriere so I saw this right away. I am running Gnome 3 if that makes any difference.
Was reverted in ports r477424. Are there still problems?
