First off, please copy and paste working code; the above has several
syntax errors, so it can't raise IndexError (or anything else for that
matter).

No, that's not the case. What happens is that the http response object
returned by urllib2.open() is read by the ClienForm.ParseResponse or
BeautifulSoup - whatever happens first - and the second call has
nothing to read.
The easiest solution is to save the request object and call
urllib2.open twice. Alternatively check if ClientForm has a parse
method that accepts strings instead of urllib2 requests and then read
and save the html text explicitly:
>>> text = urllib2.open(request).read()
>>> soup = BeautifulSoup(text)
>>> forms = ClientForm.ParseString(text)
