I have a gtk.DrawingArea as self.movie_window in my app to embed the videos from gstreamer (i use playbin...) here's my on_sync_message function (with pygtk 2.24)

def on_sync_message(self, bus, message):
        if message.structure is None:
            return
        win_id = None
        message_name = message.structure.get_name()
        if message_name == "prepare-xwindow-id":
            if sys.platform == "win32":
                win_id = self.movie_window.window.handle
            elif sys.platform == "darwin":
                print self.window.window.nsview
                win_id = self.movie_window.window.nsview
            else:
                win_id = self.movie_window.window.xid
            gtk.gdk.threads_enter()
            self.sink.set_xwindow_id(win_id)
            gtk.gdk.threads_leave()


the nsview now return the window id correctly BUT i can t play any videos... it was working when i builded gtk, gstreamer.... with x11 but now i rebuilded it all with +no_x11 +quartz and now i just have bus_error

osx crash report :
