Comment 4 for bug 1402441

Thanks for the forward.

Its package description says that Avahi is a Multicast DNS Service Discovery framework that allows programs to publish and discover services and hosts running on a local network with no specific configuration.
Maybe the indicator is trying to detect the server and the client using Avahi's service discovery capability on localhost...or in this case, Apple Bonjour's, and there could be some kind of incompatibility. However this is just my ungrounded speculation.
