[Pkg-utopia-maintainers] Bug#758384: avahi-daemon: eth0:avahi interface created although it's disconnected

[carandraug]

Package: avahi-daemon
Version: 0.6.31-4
Severity: normal

Dear Maintainer,

the avahi daemon keeps creating an eth0:avahi interface even though I have
nothing connected to eth0. Even after bringing the eth0 down, avahi brings
it back up after a few minutes.

The big problem with this is that when eth0:avahi is created, it "steals"
all other connections meaning I lose access to the internet. The result is
that a few minutes after turning on the PC, I lose internet connection. This
can be diagnosed by running 'ip route get 130.89.148.14' (www.debian.org)
which will show that eth0 is being used.

Doing 'ifconfig eth0 down' will only fix for a few minutes.

I'm unsure if this is related but this machine (Lenovo X1 carbon 2nd gen), has
a built-in gigabit ethernet port (requires an adapter).

While I understand that the *:avahi interfaces are created when it fails to get
an IP address, I'd guess it should not be creating one when it's not connected
so it uses the other interfaces (wlan0 in my case) which are working fine.
