{ 

$breadcrumbsBlock->addCrumb('home', array( 'label'=>Mage::helper('catalog')->__('Home'),

'title'=>Mage::helper('catalog')->__('Go to Home Page'),
'link'=>Mage::getBaseUrl()

// sometimes magento can't get category associated with a product 
$current_category = Mage::registry('current_category');
$current_product = Mage::registry('current_product');
if(!$current_category && $current_product){
$categories = $current_product->getCategoryCollection()
->addAttributeToSelect('name')
->setPageSize(1);
foreach($categories as $category) { 
Mage::unregister('current_category');
Mage::register('current_category', $category);
}
}
$title = array(); $path = Mage::helper('catalog')->getBreadcrumbPath();
foreach ($path as $name => $breadcrumb) 
{ 
$breadcrumbsBlock->addCrumb($name, $breadcrumb);
$title[] = $breadcrumb['label'];
