Until beginning of 2010 Python 2.6 had a special Unicode problem. You got a good chance to have downloaded a non-working Python 2.6 version.
If you still have the file descriptor problem you might uninstall Python 2.6 (and the plugins) completely and install Python 2.7 + the two required plugins as described in the FAQs section.
I don’t know if that solves the problem but it may be worth a try (needs around 10 -15 minutes).
I can’t reproduce the problem (Unicode pathnames work file with my computer) and Python 2.7 is said to be faster and more reliable anyway. 😉
