If I load the page in chrome with its resource tracking debug tab open, I can see that several files that are requested receive zero sized responses. When I loaded the page, this was for (what looks like) static files, which you say are being served by nginx. I don't see how django gets involved in this, which is probably part of the reason why you aren't getting any responses on this list. Try asking on a nginx list. As a wild stab in the dark, does it still happen when you turn sendfile off in nginx [1]? If so, that points to an OS/nginx bug.
