Okay, so now I verified that the nameserver was added to resolv.conf.
Then I rechecked before disconnecting and noted that the extra
resolv.conf entry had disappeared (without changes to network
configuration in the meanwhile). nm-tool reported the correct nameserver
address still, and it seemed to work through the local proxy (one
presumes). So the generated resolv.conf entry seems both unnecessary and
possibly transient, though as said, it has persisted beyond
disconnecting the Bluetooth PAN at least two times.

Everything working even without the entry indicates that it probably
shouldn't be generated at all.

Title:
  Using Bluetooth PAN leaves broken resolv.conf

Status in “network-manager” package in Ubuntu:
  New

Bug description:
  Having paired an Android phone, the network manager menu in Unity
  displays the "GT-I9300 Network" appropriately and I can tether over
  the phone's mobile broadband just fine.

  However, the PAN's nameserver setting is put directly into
  /etc/resolv.conf (instead of doing the dnsmasq thing) _and_ is left
  there, like so, even after disconnecting and connecting to a different
  (WiFi) network:

  # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
  #     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
  nameserver 192.168.44.1
  nameserver 127.0.1.1

  (The 127.0.1.1 part isn't there before connecting to WiFi, it is added
  at that point, but the now-defunct BT PAN nameserver address
  persists.)

  This greatly interferes with DNS queries.
