Description Lauro Moura 2010-01-21 13:55:58 EET

The example pysideqplayer.py locks up when creating the first path:

class QPlayer(QtGui.QWidget):

    def __init__(self):
        #QtGui.QWidget.__init__(self)
        super(QPlayer, self).__init__()
        self.audioOuptut=Phonon.AudioOutput(Phonon.MusicCategory, self)
        self.player=Phonon.MediaObject(self)
        Phonon.createPath(self.player, self.audioOuptut)

Relevant backtrace during the lock:
