** Description changed: - 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". + [Impact] + * Some users are unable to use parole because the pulseaudio backend cannot be opened. + * The upload fixes this issue by adding gstreamer1.0-pulseaudio to recommends. Most (all?) ubuntu distributions use pulseaudio as a backend, so this can help future users as well. + + [Test Case] + * On a clean system, run parole and try to open a video file. + * The error "Gstreamer backend error, could not initialise supporting library" may be displayed, preventing the user from viewing their media. + + [Regression Potential] + * This upload adds a single gstreamer1.0 backend to recommends, so the risk of regression is slim to none. + + [Original Bug Details] + 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".

The workaround is to install "gstreamer1.0-pulseaudio" manually.
