ClutterGst Segfaulting

[katastrophal]

I'm at a loss. This is the first time I've tried python and gtk and I don't know what's wrong. This code is based on the video tutorials at http://vimeo.com/26452876

I've tried it myself and it kept segfaulting, I've typed it from the video -letter-by-letter- and it still segfaults. I'm on Fedora 17 and don't know what's wrong. This code should just paint the window (built with glade: 2 boxes, a play button and a progress bar), set up a clutter stage and show that to me. As soon as I import ClutterGst or initialize it, it segfaults... What's wrong with that?

#!/usr/bin/env python

from gi.repository import Gtk, Clutter, GtkClutter, ClutterGst
import os, sys

UI_FILE = "Video-Player.ui"

class VideoPlayer:
    def __init__(self):
        self.builder = Gtk.Builder()
        self.builder.add_from_file(UI_FILE)
        self.builder.connect_signals(self)

        self.progress = self.builder.get_object('progress')
        self.button = self.builder.get_object('button')
        
        clutter_widget = GtkClutter.Embed()
        clutter_widget.set_size_request(600, 400)
        
        self.videotexture = ClutterGst.VideoTexture()
        
        stage = clutter_widget.get_stage()
        stage.set_color(Clutter.Color())
        
        stage.add_actor(self.videotexture)
        stage.show_all()
        
        box = self.builder.get_object('box')
        box.add(clutter_widget)
        box.reorder_child(clutter_widget, 0)
        
        
        self.window = self.builder.get_object('window')
        self.window.show_all()
        
    def destroy(self, window):
        Gtk.main_quit
        
def main():
    GtkClutter.init(sys.argv)
    ClutterGst.init(sys.argv)
    app = VideoPlayer()
    Gtk.main()
    
if __name__ == "__main__":
    sys.exit(main())

I have the same problem with Ubuntu. I have installed all the packages. It worked some time ago, but it doesn't work any more...
