Python SSL: WRONG_VERSION_NUMBER (_ssl.c:590) using urllib with a proxy

Question

This code used to run flawlessly. I haven't changed anything but tried using it from a different location, behind a proxy, and I get this error:

IOError: [Errno socket error] [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:590)

Here's where it fails:

gcontext = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
data = urllib.urlopen("https://itunes.apple.com/us/rss/topfreeapplications/limit=50/genre=" + str(category) + "/json", "download.txt", context = gcontext).read()

I immediately thought that the problem might come from the proxy I'm using, but don't know how to tell python to use that proxy as well. The solutions in this thread did not help me (same error).

And here's the full traceback:

Thanks a lot for your help!
