title: zlib_decode(): data error using composer in the doctrine2 tutorial
body: <p>UPDATE:
  I posted this issue to the bug tracker a while ago as suggested in comments, and now I ran a clean installation of the new version of composer (Composer version 7131607ad1d251c790ce566119d647e008972aa5 2014-05-27 14:26:24) and the issue is fixed.</p>
  
  <p>ORIGINAL POST:
  I'm trying to learn how to use doctrine2 using their tutorial at <a href="http://docs.doctrine-project.org/en/latest/tutorials/getting-started.html" rel="nofollow">http://docs.doctrine-project.org/en/latest/tutorials/getting-started.html</a></p>
  
  <p>but for some reason I get this error when trying to run <code>composer install</code>:</p>
  
  <pre><code>  [ErrorException]           
    zlib_decode(): data error
  </code></pre>
  
  <p>Here is the contents of composer.json:</p>
  
  <pre><code>{
      "require": {
          "doctrine/orm": "2.4.*",
          "symfony/yaml": "2.*"
      },
      "autoload": {
          "psr-0": {"": "src/"}
      }
  }
  </code></pre>
  
  <p>EDIT: PHP Version 5.5.9.</p>
  
  <p>EDIT: output of <code>composer install -vvv</code>:</p>
