[Jim Hodapp <1442473@xxxxxxxxxxxxxxxxxx>]

In my opinion, I don't think it's proper to address this at the
qtubuntu-media level since the decisions around this behavior really lie
with each application. To accommodate this would be to massively change
the way qtubuntu-media is implemented potentially introducing
significant regressions. The indicator should fix this specific issue.

Bug description:
  phablet@ubuntu-phablet:~$ system-image-cli -i
  current build number: 166
  device name: mako
  channel: ubuntu-touch/devel-proposed
  alias: ubuntu-touch/vivid-proposed
  last update: 2015-04-09 16:57:42
  version version: 166
  version ubuntu: 20150409

  version custom: 20150409

  This is specially annoying as it happens every time you change the
  volume without an active notification. Side effect is that it fires up
  media-hub, that initializes gstreamer for not really playing anything.

  Just press volume up/down and check the unity8/media-hub logs:
