ofono was actually changed to allow GPRS contexts with empty
AccessPointNames to be used for data connections.  Changing this to
Invalid.

** Changed in: network-manager (Ubuntu)
       Status: New => Invalid

Title:
  NM tries to activate contexts with empty AccessPointName attributes

Status in network-manager package in Ubuntu:
  Invalid

Bug description:
  Network Manager tries to activate ofono contexts for mobile data even
  if the AcessPointName attribute of the context is empty.  Instead,
  Network Manager should ignore such contexts.

  Reproduced on mako / #u148.

  In order to reproduce, you need to do the following:

  - Stop ofono

  # stop ofono

  - Edit ofono's gprs settings file so that it contains a single context
  with a blank AccessPointName.

  # cd /var/lib/ofono/<ISMI>
  # edit gprs file:

  [Settings]
  Powered=true
  RoamingAllowed=false

  [context1]
  Name=default
  AccessPointName=
  Username=
  Password=
  Type=internet
  Protocol=ip

  - Reboot the phone

  Notice that NetworkManager attempts to activate the context.  Here's a
  snippet from my phone when I run the above steps ( albeit with a
  different context name ):
