title: Why var_dump a Doctrine Objects kill my Apache?
body: <p>I have a very strange problem, when I try to <code>var_dump</code> (or <code>print_r</code>) a Doctrine Object, my Apache responses with an empty blank page (200 OK header). I can <code>var_dump</code> a normal php var like:</p>
  
  <pre><code>$dummy = array("a" =&gt; 1, "b" =&gt;2);
  </code></pre>
  
  <p>And it works fine. But I can't with any object from any Doctrine class, (like a result from <code>$connection-&gt;query()</code>, or an instance of a class from my object model with Doctrine).</p>
  
  <p>Anybody knows why this happens?</p>
