dbus[991]: [system] Failed to activate service 'org.freedesktop.Avahi': timed out

This means that it failed to connect to the service since it's not running. The 30 seconds you spend waiting is not because the service is starting, is because another process expects the service to be running when dbus tries to access the key. If you want to really stop Avahi you should instead remove the package:

sudo apt-get remove avahi-daemon

There isn't a sane way to deactivate the daemon without messing with other networking services.
