What I found was that notify::action was enough to catch most of what
I needed. At first I didn't think it was working properly because I
wasn't seeing the signal when switching from Measure to the Desktop.
But as soon as I switched to a different activity, I see the
notification. So unless the Desktop (or Journal or Neighborhood) need
to access gstreamer, I think we are OK.
