I don't think this is the right fix. The MDNS client is
supposed to already deal with the case where Avahi is not
running. It should be registering a DBus watch, which will
result in a notification when Avahi later starts up. At
which point we should register. Something in this process
is not working, and so just ignoring the error is not
right IMHO
