Comment 10 for bug 266543

After applying this patch to 2.0.5, I found that I had to
add this line manually to my existing config file
$prefix/Mailman/mm_cfg.py...

DEFAULT_FORCE_PLAIN_TEXT = 0

If this line is not added, any web requests and any
messages posted will produce an error "AttributeError :
DEFAULT_FORCE_PLAIN_TEXT".

Not sure if I did something wrong or if this is normal, but
I wanted to advise others just in case
