Python 2.7.9, 3.4.2 won't verify SSL cert for "verisign.com"

[Laura Creighton]

I am away on a consulting gig, so I really only have my laptop to test on.

Python 2.7.8 (default, Nov 18 2014, 14:57:17)
debian version jessie/sid
SSL test, with OpenSSL version OpenSSL 1.0.1j 15 Oct 2014.
Connection to "verisign.com" failed: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581).

Connection to "www.verisign.com" failed: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581).

Connection to "python.org" succeeded.

---------------------

Python 3.4.2 (default, Nov 13 2014, 07:01:52)
debian version jessie/sid
SSL test, with OpenSSL version OpenSSL 1.0.1j 15 Oct 2014.
Connection to "verisign.com" failed: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581).

Connection to "www.verisign.com" failed: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581).

Connection to "python.org" succeeded.
---------------
openssl s_client -connect www.verisign.com:443 -CAfile cacert.pem

succeeds

.....

So whatever problem there is, I have it too.
