Using the object GstPlayBin function causes a RuntimeError exception on python.
I am using Ubuntu 12.10 with Gstreamer 0.11.91-2.

This is the exaple code:

#!/usr/bin/env python
# -*- coding: utf-8; tab-width: 4; mode: python -*-
# emacs: -*- mode: python; py-indent-offset: 4; indent-tabs-mode: t -*-
# vi: set ft=python sts=4 ts=4 sw=4 noet 

import sys

import gi
try:
    gi.require_version('Gst', '1.0')
    from gi.repository import Gst
except ValueError:
    print 'Could not find required Gstreamer 1.0 library.'
    sys.exit(1)

# Setup GStreamer 
Gst.init(None)
Gst.init_check(None)
print Gst.version_string(), Gst.version()

if Gst.ElementFactory.find('playbin'): # filesrc
    player = Gst.ElementFactory.make('playbin', 'MultimediaPlayer')

    if player == None:
        print 'Error: could not create the player'
        sys.exit(1)
    else:
        print 'Player element', player.element
else:
    print 'Error: could not find the playbin plugin for gstreamer'
    sys.exit(1)

Running the example shows this traceback

GStreamer 1.0.0 (1L, 0L, 0L, 0L)
Player element
Traceback (most recent call last):
  File "/home/shakaran/gst_player_element.py", line 28, in <module>
    print 'Player element', player.element
RuntimeError: unable to get the value
