Steve is right. Setting up a default route on a link-local interface is inherently flawed.
The default route is the the "gateway of last resort", i.e., the router address used when no other known route exists for a given IP packet's destination address. However, the basic architectural assumption of link-local networks is that no routable address is configured. Thus, by definition, no routers or dhcp servers are available to the interface. Consequently, it makes no sense for avahi-autoipd to assign a default route. Worse, when the host has multiple interfaces, avahi interferes with standards-compliant network connections to the internet. (For example, the host has both a wired NIC connected to routeable network and a wireless card either not connected or connected only to a local printer.) Avahi-autoipd's assignment of a default route will result in multiple default routes (one from it and one from the actual router), causing connectivity to the internet to break. See, e.g., http://ubuntuforums.org/showthread.php?p=4501456 (noting that the best solution is to purge avahi and its cousins).
