I just reproduced this bug on a pristine saucy VM running MAAS: 1.4+bzr1701+dfsg-0+1727+212~ppa0~ubuntu13.10.1
After I installed MAAS (apt-get install maas maas-dns maas-dhcp), both avahi-daemon and dbus services were not running causing the same error in apache logs I originally posted in this bug.
