I've been looking at this on Wily with a user suffering the bug, and it
looks at first glance to be a timing issue - namely, that NM doesn't
wait long enough after starting dnsmasq to query the name on the bus.

The code is Ubuntu specific, and introduced via

debian/patches/0001-dns-use-DBus-to-make-dnsmasq-nameserver-
changes.patch

Title:
  "dnsmasq not available on the bus"

Status in network-manager package in Ubuntu:
  Confirmed

Bug description:
  Dnsmasq seems to be having some issues. This occurs whenever I try to
  connect to my wireless network; sometimes it only happens once, but
  sometimes the error loops for a while.
