mac findertools restart() does not work?

[nate]

>>> import findertools
>>> findertools.restart()
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File
"/Library/Frameworks/Python.framework/Versions/2.4//lib/python2.4/plat-mac/findertools.py",
line 90, in restart
    finder.restart()

line 29, in restart
    raise aetools.Error, aetools.decodeerror(_arguments)
aetools.Error: (-1708, 'the AppleEvent was not handled by any handler',
None)

does anyone know why findertools.restart() isn't working on my machine
(see above code), is there something more I need to do?
