wxPython.lib.dialogs.fileDialog() crashes python

Hi ppl,

I'm new to the list. I've just started using wxPython and here's my first problem:

from wxPython.lib import dialogs
dialogs.fileDialog()

crashs the python interpreter.
I'm on w2k and this happens w/ all combinations of wxPython 2.4.1.2 / 2.4.1.2u and python 2.2.2 / 2.3
