I _think_ the IP address is coming from Avahi; it loses it's connection
& when it no longer has a DHCP IP, the interface is assigned a
non-routed reserved local IP address (169.254.x.x).

$ cat /etc/networks
# symbolic names for networks, see networks(5) for more information
link-local 169.254.0.0

Given your configuration, I'd just go ahead and configure the machine
for a fixed IP.
