while trying a debug an ivr problem, i started from a slightly modified
apps/examples/ivr_examples/tmpfile.py:

from ivr import *
import os
class IvrDialog(IvrDialogBase):

        def onSessionStart(self, hdrs):
                f = open("/tmp/default_en.wav")
                audio = f.read()
                fp = os.tmpfile()
                fp.write(audio)
                fp.seek(0)
                wav = IvrAudioFile()
                wav.fpopen("tmp.wav", AUDIO_READ, fp)
                self.enqueue(wav, None)

however, when i run it, i get
