Nginx Django csrf_token get 502 error invalid header

I have a Django site developed using Pinax. When I deploy it in apache+mod_wsgi, it works fine. But when I deploy it in nginx+uwsgi, it nearly works fine, but the page includes a {% csrf_token %} tag. The crashed page dose not display a Django error page, but displays an Nginx 502 error page. The Nginx error log is:

2012/06/08 09:11:59 [error] 30224#0: *79 upstream sent invalid header while reading response header from upstream, client:, server:, request: "GET /discuss/ HTTP/1.1", upstream: "uwsgi://", host: "", referrer: ""

uwsgi displays:

{address space usage: 42319872 bytes/40MB} {rss usage: 22573056 bytes/21MB} [pid: 21398|app: 0|req: 1/3] () {42 vars in 988 bytes} [Fri Jun 8 18:27:01 2012] GET /discuss/ => generated 31139 bytes in 2306 msecs (HTTP/1.1 200) 5 headers in 358 bytes (1 switches on core 0)

The error occurs on a GET request, not a POST request. I tested this - when I delete the csrf_token token from the template, it's OK. So, there must be a relationship between the token and the error, not anything else.

What's going on?


Okay, it's solved. I had installed uwsgi by compiling the source. Now I delete that version, and reinstall it using pip install uwsgi, and everything is fine!
