ConfigParser doesn't prevent "manually" adding a section named DEFAULT;
however, doing so creates a duplicate, inaccessible [DEFAULT] section in
the config file:
>>> import sys, ConfigParser
>>> c = ConfigParser.ConfigParser()
>>> c.add_section('DEFAULT')
>>> c.write(sys.stdout)

>>> c.set('DEFAULT', 'color', 'yellow')
>>> c.write(sys.stdout)
color = yellow


It seems that the correct thing to do would be to disallow

Care to provide a patch?

Otherwise this may be a good bug day candidate.  The next one's Jan 19.

It's an easy task for the bug day unless you can provide a patch and an
unit test earlier.

Please see cfgparser.diff for the fix. It has tests and doc change.

I should add that the patch disallows not only 'DEFAULT' but all other
variants such as "Default" and "default". I am not entirely sure if my
description of this behaviour as "DEFAULT or any of it's
case-insensitive variants".

I tested the patch and works very well. I modified "Misc/NEWS" file 
beacuse the change wasn't reported and I uploaded diff file
