What is this traceback error in Python?

Question

Traceback:
File "/usr/local/lib/python2.6/dist-packages/django/core/handlers/base.py" in get_response
  92.                 response = callback(request, *callback_args, **callback_kwargs)

Exception Type: CannotSendRequest at /linkedin/auth
Exception Value: 

More specifically, it is occuring in this function:

def fetch_response(oauth_request, connection, linkedin_getinfo = False, other_url = ''):
    url = oauth_request.to_url()
    if linkedin_getinfo:
        headers = oauth_request.to_header()
        connection.request(oauth_request.http_method,other_url, headers = headers)
    else:
        connection.request(oauth_request.http_method,url)
    response = connection.getresponse()
    s = response.read()
    return s
