I have put the patch here:
 http://paste.debian.net/105005/

So, NetworkManager checks if somebody is listening to the right DBus
address. With Debian and systemd, since dnsmasq is DBus enabled, it will
be started at this point. Otherwise, the patch also tries to run dnsmasq
itself.

Then, there is another patch to use a "private" DBus name to avoid using
dnsmasq from the system I suppose. The relevant entry is here:

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.
    Also set the dnsmasq DBus service name to our own custom name:
    org.freedesktop.NetworkManager.dnsmasq, which will also avoid conflicting
    with other dnsmasq instances which might have --enable-dbus enabled.
    (LP: #1034946)

Maybe Mathieu (in copy) can tell us if this has been forwarded upstream.

The patch is here:
