title: Items are overlapped in layout of category page in Joomla (due to container height attribute)
body: <p>I'm developing a website using Joomla 3.2.1, K2 and creativia template.
  I've already done quite a lot of customization and everything works fine.
  I've only one, big problem.
  When I select a category to have a list of items, it results in a mess of overlapped images (meaning that all items are displayed but the layout does not work).
  If I simply reload the page (or even open firebug to check the page properties), everything is back correctly to his place.</p>
  
  <p>You can check the problem here:

  <p>Just open the menu item Architettura or Grafica (it happens from time to time).</p>
  
  <p><strong>EDIT</strong>: From further investigation I found that the attribute <code>height</code> in the <code>container</code> DIV changes quite randomly when loading the page.
  If I get a small value, then everything is messed up.
  It seems to be something related to a timing in evaluating that value (which is calculated dynamically).</p>
  
  <p>How can I fix that?</p>
