Bug Description

When trying to access some sites over https, both python and perl in precise fall over.
Here's what happens with libwww-perl's GET:
$ GET "https://one.ubuntu.com/" | head -n1
<!DOCTYPE html>
$ GET "https://api.dailymotion.com/user/SFLTV/features?fields=url,thumbnail_small_url,title,description&limit=100&page=1"
Can't connect to api.dailymotion.com:443

LWP::Protocol::https::Socket: SSL connect attempt failed with unknown errorerror:14077102:SSL routines:SSL23_GET_SERVER_HELLO:unsupported protocol at /usr/share/perl5/LWP/Protocol/http.pm line 51.

Python throws essentially the same error. These work in lucid, and were working in precise, until very recently.

I don't get this issue in wget, curl or openssl

But I do get this issue in python and GET

import requests
requests.post("https://browserid.org/verify", data={})

I am attaching two files to add more information to this bug. I used ssldump to capture the handshake between the client machine and https://browserid.org to see where there were differences. I am using Ubuntu 12.04 32bit.

The file named curl_capture.txt is captured from a curl https://browserid.org
The file named GET_capture.txt is captured from GET https://browserid.org

I'm not sure if it's related, but I get the similar error:

urllib2.URLError: <urlopen error [Errno 1] _ssl.c:504: error:140773E8:SSL routines:SSL23_GET_SERVER_HELLO:reason(1000)>

My case may be related be related to http://bugs.python.org/issue11220, but the suggested fix of using a custom opener to switch to SSLv3 only results in the error httplib.BadStatusLine: ''.

I'm using Python 2.7.3 on Ubuntu 12.04.
