Nuvola Player doesn't start on Arch Linux

[Harshit]

I have a completely updated Arch Linux x86_64 installed from August 2013 snapshot. Nuvola Player 2.1.0 fails to start. Here's the debug output.

It seems WebKitGTK library on your system has been built with GStreamer 1.0
API, but Nuvola Player has been built with GStreamer 0.10. You have to
rebuild Nuvola Player with GStreamer 1.0 API. See file INSTALL for details.
