Bug description:
  Test Case
  ---------
  You can duplicate this with the daily build. If you install, don't select the option to install additional codecs.

  If you've already installed the additional codecs, you can remove them
  with

  sudo apt purge ubuntu-restricted-addons gstreamer1.0-fluendo-mp3 \
  gstreamer1.0-libav gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly;
  sudo apt autoremove

  Here's a CC-BY-ND .mp3 you can download:
  http://music.esgi.co.uk/track/echoes-in-time

  Use totem (or rhythmbox) to try to open the file.

  Original Bug Report
  --------------------
  Attempting to play a mp3 file with Rhythmbox on the latest Zesty daily build

  Rhythmbox opens but no playback start.
  On the terminal I got this:

  Rhythmbox-Message: Missing plugin: gstreamer|1.0|rhythmbox-metadata|MPEG-1 Layer 3 (MP3) decoder|decoder-audio/mpeg, mpegversion=(int)1, mpegaudioversion=(int)1, layer=(int)3
  /usr/lib/python3/dist-packages/sessioninstaller/core.py:47: PyGIWarning: Gst was imported without specifying a version first. Use gi.require_version('Gst', '1.0') before import to ensure that the right version gets loaded.
    from gi.repository import Gst
  /usr/lib/python3/dist-packages/sessioninstaller/core.py:48: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version('Gtk', '3.0') before import to ensure that the right version gets loaded.
    from gi.repository import Gtk
  Falling back to package information
  Rhythmbox-Message: Missing plugins installed. Updating plugin registry ...

  But the wizard to install the missing codec actually fails to launch.
