SPDY bug: gzip_static doesn't work

[Tom van der Woerdt]

Bug summary:
   Cannot use gzip_static when spdy is enabled. Removing spdy from the 
configuration restores previous functionality.

Steps to reproduce:
   * Sample location directive:
      location = /style.css {
        alias /path/to/style.css;
        gzip_static on;
        expires 24h;
      }

   * Ensure style.css.gz exists and style.css does not
   * Navigate to the site and notice that there's no stylesheet (use 
Firefox)

Error log:
   2012/06/24 14:03:15 [error] 12823#0: *3127 open() 
"/path/to/style.css" failed (2: No such file or directory) while SSL 
handshaking, client: my.ip.goes.here, server: example.com, request: "GET 
/style.css HTTP/1.1", host: "example.com", referrer: "https://example.com/"

Notes:
   Bug only seems to affect Firefox, not Chrome
   SPDY spec mentions that all clients MUST support gzip, so there's no 
reason for this request to fail
