Works for me under Fedora using ext3 as the file system.

$ python2.6
Python 2.6.1 (r261:67515, Dec 24 2008, 00:33:13)
[GCC 4.1.2 20070502 (Red Hat 4.1.2-12)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

Given that chr(255) is a valid filename on my file system, I would 
consider it a bug if Python couldn't deal with a file with that name.
