I've seen something like this: The requests module http://docs.python-requests.org/en/latest/ ships with its own set of certificates "cacert.pem" and ignores the system wide ones -- so, for instance, adding certificates to /etc/ssl/certs on your debian or ubuntu system won't work. I edited it by hand and then changed the REQUESTS_CA_BUNDLE environment variable to point to it.
Perhaps your problem is along the same lines? Laura -- https://mail.python.org/mailman/listinfo/python-list
