MidiToText : EventDispatcher instance has no attribute 'sysex_events'

[tim]

Trying to convert midi to text using MidiToText.py.
I get the following:

midi_port: 0
Traceback (most recent call last):
  File "MidiToText.py", line 176, in ?
    midiIn.read()
  File "C:\Python24\Lib\site-packages\midi\MidiInFile.py", line 24, in read
    p.parseMTrkChunks()
  File "C:\Python24\Lib\site-packages\midi\MidiFileParser.py", line 167, 
in parseMTrkChunks
    self.parseMTrkChunk() # this is where it's at!
  File "C:\Python24\Lib\site-packages\midi\MidiFileParser.py", line 129, 
in parseMTrkChunk
    dispatch.sysex_events(sysex_data)
AttributeError: EventDispatcher instance has no attribute 'sysex_events'

any ideas?
thank you,
Tim
