Comment 32 for bug 458904

This is now working, *but* upgrading to the latest package is not enough to fix it on a running system. You need to restart avahi-daemon (to make it pick up the new avahi-daemon.conf) before you restart eucalyptus (and the publication takes place). Rebooting would also work, as it would restart both.

upgrade to 7.2 (which restarts eucalyptus): test = FAIL
  then restart avahi-daemon : test = FAIL
  then restart eucalyptus : test = PASS

upgrade to 7.2, reboot: test = PASS

If that's not acceptable, I'd suggest postinst should pick up that upgrade path and restart avahi before the eucalyptus publication jobs are restarted.
