BTW, change:

	<Location /your/directory>
		PythonPath ['/var/www/python/htmlatex']+sys.path
		PythonDebug Off
		PythonOutputFilter htmlatex HTMLATEX
		AddOutputFilter HTMLATEX .htmlx
	</Location>


to:

	<Location /your/directory>
		PythonPath ['/var/www/python/htmlatex']+sys.path
		PythonDebug Off
		PythonOutputFilter htmlatex HTMLATEX
		AddOutputFilter HTMLATEX;CONTENT_LENGTH .htmlx
	</Location>

and you will get correct amended content length header added back in.

This works because you buffer up data and write it in one go. Thus the
CONTENT_LENGTH output filter is able to recalculate content length
for you.

You could also have added it yourself by going:

    if s is None:
        temp_doc = ''.join(temp_doc)
        data = main(temp_doc)
        filter.req.set_content_length(len(data))
        filter.write(data)
        filter.close()
