Nothing to do with the This signal will not be emitted by default, you
have to set up gst_bus_sync_signal_handler() as a sync handler if you
want this signal to be emitted when a message is posted on the bus, like
this: I read in the documentation?
(just a guess, I'm not an expert about gstreamer)

Hi Pietro,
Thanks for your response.
Your response seems to be right, but it doesn't work on GTK3 with PyGi
This line should enable the signal for the emission.
bus.enable_sync_message_emission()
The Gnome Bug #631901 shows that there is a problem with the signals
emitted:
https://bugzilla.gnome.org/show_bug.cgi?id=631901
message::eos, message::error and sync-message::element are not emitted,
just message and sync-message without members.
Maybe it is a problem with MiniObject support through GI.

http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstMiniObject.html#GstMiniObject
Using bus.connect('message', self.on_message)
and
def on_message(self, bus, message):
print('message: {!r}'.format(message))
it show this traceback on close:
Traceback (most recent call last):
File test.py, line 62, in on_message
print('message: {!r}'.format(message))
TypeError: unknown type GstMessage
Also I found:
gst_bus_create_watch, since GSource aren't wrapped in pygtk
gst_bus_sync_signal_handler and gst_bus_async_signal_func since
these functions are used by the default bus handler anyway.

Re: [pygtk] PyObject fails with Gst on signal sync-message::element
Hi,
what version of GStreamer are you using? I think only 0.11 (future
1.0) can be used through introspection. There are other programs that
are being ported to introspection and that use GStreamer, such as
Pitivi, I would look at them for ideas.
Regards,
Tomeu

Could you provide me more info about 0.11?
