Title:
  Bluetooth DUN stopped working

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

Bug description:
  I've had dial-up networking via bluetooth working between my CR-48 and
  Blackberry 9800 for several months.

  Recent Precise update (sometime around the last couple of weeks of
  2011) appear to have broken the ability to tether over bluetooth in
  this manner.  I have completely removed the bluetooth connection and
  re-paired the devices from scratch, but it does not work.

  Other bluetooth functionality appears to work fine.  i.e. I can send
  files from the laptop to the phone without issue.

  Here's what I see in syslog:

  dmesg is devoid of any errors during the attempt to connect.  The only
