What do you mean by "dies" ?
Are you able to download any static file from nginx ?

By the way, it's better to use this configuration:

     location / {
         try_files  $uri  $uri/  @unicorn;
     }

     location @unicorn {
         proxy_pass http://unicorn;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         proxy_set_header Host $host;
         proxy_redirect off;
     }
