The bug (in the network-manager package) is that /etc/dnsmasq.d/network-
manager contains
except-interface=lo
despite the fact that network-manager was changed not to listen on lo's
IP address (127.0.0.1) any more. Here's the changelog entry announcing
this change.
network-manager (0.9.6.0-0ubuntu4) quantal; urgency=low
* debian/patches/dns-dnsmasq-interface-and-dbus-path.patch: set the address
dnsmasq (and bind) plugins should listen on for DNS resolution to
127.0.1.1,
as opposed to 127.0.0.1 to avoid conflicts with other instances that might
need to run on the system with that address.

If the aforementioned line is commented out
#except-interface=lo
then name service works, with the standalone dnsmasq listening on
127.0.0.1 and forwarding to 127.0.1.1. @Submitter: please use this
workaround for now. Assuming you want to use standalone dnsmasq,
remember to set /etc/default/dnsmasq ENABLED back to 1.
Earlier discussion of the issues at hand here: bug #959037.
** Package changed: dnsmasq (Ubuntu) => network-manager (Ubuntu)
** Summary changed:
- dnsmasq updating resolvconf when it's not configured to do DNS
+ network-manager dnsmasq configuration snippet causes standalone dnsmasq not
to listen on 127.0.0.1, breaking name service when dnsmasq is installed
