Ticket #499 (defect)

In xmlrpcfilter.py, there's such code to validate a XML-RPC request:

    def testValidityOfRequest(self):
        # test if the content-length was sent
        length = cherrypy.request.headers.get('Content-Length') or 0
        ct = cherrypy.request.headers.get('Content-Type') or 'text/xml'
        return int(length) > 0 and ct.lower() in ['text/xml']

The content type of a valid request might be different than 'text/xml'. for example, it can be 'text/xml;charset=UTF-8'. In such situation, the last statement:

    ct.lower() in ['text/xml']

will cause problem.
