title: Liquid for loop not working properly in Jekyll
body: <p>I'm using a liquid for loop in Jekyll to display page content based on this YAML structure:</p>
  
  <pre><code>work_left:
    isitgo:
      image: /images/isitgo.png
      caption: isitgoonair.net homepage
      description: a website
    disko:
      image: /images/disko.png
      caption: Disko
      description: a website
  work_right:
    qfi:
      image: /images/qfi.png
      caption: qfi.im
      description: a website
  </code></pre>
  
  <p>This is the for loop:</p>
  
  <pre><code>{% for item in page.work_left %}
      {{ item.image }}
  {% endfor %}
  </code></pre>
  
  <p><code>item.image</code> will not result into the strings <code>/images/isitgo.png</code> and <code>/images/disko.png</code> being output.<br>
  If instead I just do <code>{{ item }}</code>, here's the result:</p>
  
  <pre><code>isitgo
  {
      "image"=&gt;"/images/isitgo.png",
      "caption"=&gt;"isitgoonair.net homepage",
      "description"=&gt;"an awesome website i made"
  }
  
  disko
  {
      "image"=&gt;"/images/disko.png",
      "caption"=&gt;"Disko",
      "description"=&gt;"that site"
  }
  </code></pre>
  
  <p>What's causing this?</p>
