Looking at the tempfile, it contains HTML from a Squid3 error page.

From looking at Squid3's logfile, `urlretrieve` appears to do a GET request to the https URL, while wget will use CONNECT.

I am using Django's current master and Python 2.7.5+ (Ubuntu 13.10, in a virtualenv).

As a workaround I can unset $https_proxy."	Bug	closed	HTTP handling	dev	Normal	needsinfo			Unreviewed	0	0	0	0	0	0
