The Avahi code is used for some auto-configuration of client-server
connection.
I am waiting on a newer release, but at that point I expect to mark
this bug as wontfix. My reasoning will be as follows:
1. Switching to the native API is not straightforward to me.
2. I don't know that any functionality is actually affected by these
warnings. Please correct me.
3. Upstream has removed the graphical interface code (including the
auto-configuration related code using libavahi) in recent commits.
I think they won't be maintaining it any longer.
It is possible a new GUI could be released which relies on this code,
but my current understanding is that the new GUI is likely to be
closed source.
I will revisit this once there is a newer release so I have something
concrete to make a decision on.
