Public bug reported:
I use newly installed Xubuntu 14.04. When I try to open a video file,
Parole pops up a dialog box, say that "Gstreamer backend error, could
not initialise supporting library".
This is the output from the terminal, with gst debug level = 2:
somporn@somporn-P4M900T-M2:~$ parole --gst-debug-level=2 SomeVideo.webm

You'll notice that it doesn't try to use pulseaudio, cause gst to failed
to find a supported audio sink.
The workaround is to install "gstreamer1.0-pulseaudio" manually.
