Also important to note is that this bug is no longer considered to be a
blocker when syncing the RTM archive with the Vivid packages. Outside of
the noisy denial message, the fact that AppArmor is blocking unrequested
replies should not result in any breakage of software relying on D-Bus
communications.

Title:
  AppArmor unrequested reply protection generates unallowable denials

Status in dbus package in Ubuntu:
  In Progress

Bug description:
  Starting with utopic's dbus 1.8.6-1ubuntu1 package, the new AppArmor
  unrequested reply protections can generate some denials that can't
  easily be allowed in policy. For example, when running a confined
  pasaffe, you see these denials when starting and closing pasaffe:

  apparmor="DENIED" operation="dbus_error"  bus="session"
  error_name="org.freedesktop.DBus.Error.UnknownMethod" mask="send"
  name=":1.22" pid=4993 profile="/usr/bin/pasaffe" peer_pid=3624
  peer_profile="unconfined"

  It isn't obvious how to construct an AppArmor D-Bus rule to allow that
  operation. A bare "dbus," rule allows it but that's not acceptable for
  profiles implementing tight D-Bus confinement.

  The code that implements unrequested reply protections should be
  reviewed for issues and, if everything looks good there,
  investigations into how to allow the operation that triggers the above
  denial should occur.
