title: Magento: getDescription() on product gives null
body: <p>I have a little problem with Magento and I am trying to figure what's wrong for one hour and there is no end.</p>
  
  <pre><code>$this-&gt;_product = Mage::getModel('catalog/product')-&gt;load(1565);
  $desc = $this-&gt;_product-&gt;getDescription();
  </code></pre>
  
  <p>I have code like this. It's very simple, but getDescription function gives me null (also shortDescription). My product model don't have information about description (in back panel this product have both - description and short description).</p>
  
  <p>Is there something that I should add to this function? I read few topic and every of them proposes code like my to get this description.</p>
