Comment(by RafaelOrtiz):

 Ariel and me, found that there is a gst issue..


 452         try:
 453             pipe = gst.parse_launch(pipeline)
 454             bus = pipe.get_bus()
 455             bus.add_signal_watch()
 456             bus.connect('message', gstmessage_cb, pipe)
 457             pipe.set_state(gst.STATE_PLAYING)

 commenting this code seems to fix the problem, but the code needs to be
 changed, as we saw it gst is being run inside a thread to use espeak, and
 this call to espeak in the thread doesn't have all the needed
 configuration for espeak that is in speaker.py.
