title: Assetic failed in dev environment
body: <p>I'm trying to run <code>assetic:dump</code> from Symfony2 shell but it stops at some point and hangs there, this is the message I get:</p>
  
  <blockquote>
    <p>[error] The source file
    "/var/www/html/app/../vendor/twbs/bootstrap/fonts/glyphicons-halflings-regular.eot"
    does not exist.</p>
  </blockquote>
  
  <p>I used MopaBootstrapBundle in the past but I non longer needed so I remove it and after that I run all this commands:</p>
  
  <pre><code>Symfony &gt; cache:clear
  Clearing the cache for the dev environment with debug true
  Symfony &gt; cache:warmup
  Warming up the cache for the dev environment with debug true
  Symfony &gt; assetic:dump --watch
  Dumping all dev assets.
  Debug mode is on.
  
  [error] The source file "/var/www/html/app/../vendor/twbs/bootstrap/fonts/glyphicons-halflings-regular.eot" does not exist.
  </code></pre>
  
  <p>Any advice? What I'm doing wrong?</p>
  
  <p><strong>Adding assetic config at <code>config.yml</code></strong></p>
