This seems to be an issue with how gst-plugin-scanner loads python. On an
older machine that works you will have a .gstreamer folder in your home
directory which stores the plugin cache. Perhaps if you were to copy this
to your other machine it would also get stuff loading.

We had implemented a fix to make the gstreamer plugin in question try to
load python from bundle location and not from the system. As Antoine said
you can view the open ticket that I've been working on and any help is
appreciated as I am not an OSX user myself.
