please note a couple of things:

- this mailing list is not for reporting general bugs on Python, but
only for its documentation
- Python 2.6.5 is in security fix-only mode, so no general bugfixes
are performed on this release, so you probably would like to update to
python 2.7 or even to the current Python3 stable release, 3.2

Could you please file an issue on http://bugs.python.org/ , possibly
with a sample code to replicate this problem? I've tried with 2.7, but
I was only able to replicate it removing explicitly the filename.
