tricky.

In 1.6 and later, Tk (and Tkinter) uses Unicode throughout.
Return values from Tk are returned as ordinary strings if they
only contain ASCII characters, and Unicode strings otherwise.

The problem here is that the os.stat function don't know what
to do with a Unicode string that contains non-ASCII characters
(this is true for both 1.6final and 2.0b1).

:::

The right way to fix this is to teach os.stat (and all the other
stdio/posix functions) to convert unicode to 8-bit strings using
the system encoding (as returned by locale.getdefaultlocale())

:::

But for now, it's probably easier to fix this in IDLE or maybe in
the Tkinter interface layer.  try changing the _fixresult method
in Lib/lib-tk/tkFileDialog.py to (untested):

    def _fixresult(self, widget, result):
        if result:
            # use system encoding for filenames
            import locale
            lang, encoding = locale.getdefaultlocale()
            result = result.encode(encoding)
            # keep directory and filename until next time
            import os
            path, file = os.path.split(result)
            self.options["initialdir"] = path
            self.options["initialfile"] = file
        self.filename = result # compatibility
        return result
