This issue was fixed in Ubuntu 16.04 LTS in apparmor 2.10.95-0ubuntu2.2
(by way of 2.10.95-0ubuntu2.1, which was superceded in xenial-proposed).
Marking that task closed.

** Changed in: apparmor (Ubuntu Xenial)
       Status: In Progress => Fix Released

Title:
  Apps can't connect to the user's session bus, even though it exists

Status in apparmor package in Ubuntu:

Status in apparmor source package in Xenial:

Bug description:
  [Impact]

  Systemd user sessions makes telepathy unhappy because access to
  /run/user/<nnn>/bus is denied

  [Test Case]

  $ sudo apt install dbus-user-session empathy

  Restart the session (or reboot) and then start empathy:

  $ empathy

  In 16.04, you may need to set correctly DBUS_SESSION_BUS_ADDRESS
  before launching empathy:

  $ DBUS_SESSION_BUS_ADDRESS="unix:path=/run/user/1000/bus" empathy

  Without this bug fix, empathy fails with "Error contacting the account
  manager", and dmesg shows several denial messages like so:

  [ 63.960358] audit: type=1400 audit(1469458539.595:27):
  apparmor="DENIED" operation="connect" profile="/usr/lib/telepathy
  /mission-control-5" name="/run/user/1000/bus" pid=4563 comm="mission-
  control" requested_mask="wr" denied_mask="wr" fsuid=1000 ouid=1000

  [Regression Potential]

  None. The fix simply adds permissions to the dbus-session-strict
  abstraction. This change will not introduce any new AppArmor denials
  since policy is being loosened instead of being restricted.
