Fontawesome + rails 4.0.1 не работает

Я использую fontawesome 3.2.1 и bootstrap 3.0.0 в моем проекте rails 4.0.1. Все мои активы находятся в поставщике/активах.

проблема заключается в том, что мой fontawesome работает в режиме разработки, когда я компилирую свои активы (производство env) и запускаю сервер в производственном env, не имея возможности загрузить font-size. ошибки равны

Started GET "/assets/fontawesome-webfont.svg" for 127.0.0.1 at 2014-01-08 11:48:55 +0530

fontawesome загружаются в font-awesome.css как

@font-face {
  font-family: 'FontAwesome';
  src: url('/assets/fontawesome-webfont.eot?v=3.2.1');
  src: url('/assets/fontawesome-webfont.eot?#iefix&v=3.2.1') format('embedded-opentype'), url('/assets/fontawesome-webfont.woff?v=3.2.1') format('woff'), url('/assets/fontawesome-webfont.ttf?v=3.2.1') format('truetype'), url('/assets/fontawesome-webfont.svg#fontawesomeregular?v=3.2.1') format('svg');
  font-weight: normal;
  font-style: normal;
}

глификоны загружаются в bootstrap.min.css как

@font-face{
  font-family:'Glyphicons Halflings';
  src:url('/assets/glyphicons-halflings-regular.eot');
  src:url('/assets/glyphicons-halflings-regular.eot?#iefix') format('embedded-Opentype'), url('/assets/glyphicons-halflings-regular.woff') format('woff'),url('/assets/glyphicons-halflings-regular.ttf') format('truetype'),url('/assets/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg')}

Я попробовал пару решений, таких как добавление "font" или "assets" к "url", но никто не работал.

- UPDATE

содержимое config/application.rb

config.assets.enabled = true
config.assets.version = '1.0'

config.assets.paths += ["#{config.root}/vendor/assets/fonts", "#config.root}/app/assets/images/**", "#{config.root}/vendor/assets/images"]
config.assets.precompile += %w(*.png *.jpg *.jpeg *.gif *.eot *.svg *.ttf *.otf *.woff vendor/assets/stylesheets/**/* vendor/assets/fonts/*)

["#{config.root}/vendor/assets/javascripts", "#config.root}/vendor/assets/stylesheets"].each do |d|
config.assets.precompile += Dir.glob("#{d}/*").map{|f| "#{f.gsub(d + '/', '')}/**/*" if File.directory?(f)}.compact
