title: Magento: Get the parent category of the current store/website
body: <p>I'm using <a href="http://www.magentocommerce.com/boards/viewthread/176389/P15/#t369242" rel="nofollow">this code</a> to display the parent categories of a product in the breadcrumbs.</p>
  
  <p>Unfortunately this doesn't work with multi store setups where a product is additionally assigned to a category which doesn't exist in the current store. Example:
  On <a href="http://www.geschenkhexe.ch/kugelschreiber-kamera.html" rel="nofollow">this product page</a> the breadcrumb links to the category "Minikameras" which actually is a category of another website/store.</p>
  
  <p>What's the best way to display only categories of the active website/store?</p>
