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
