After installation, after trying to reindex catalog_url the following error shows up:

Uncaught TypeError: Argument 2 passed to Loewenstark_UrlIndexer_Model_Url::_refreshProductRewrite() must be an instance of Varien_Object, boolean given, called in /var/www/html/app/code/core/Mage/Catalog/Model/Url.php on line 562 and defined in /var/www/html/app/code/community/Loewenstark/UrlIndexer/Model/Url.php:87\nStack trace:\n#0 /var/www/html/app/code/core/Mage/Catalog/Model/Url.php(562): Loewenstark_UrlIndexer_Model_Url->_refreshProductRewrite(Object(Varien_Object), false)\n#1 /var/www/html/app/code/core/Mage/Catalog/Model/Url.php(255): Mage_Catalog_Model_Url->refreshProductRewrites('4')\n#2 /var/www/html/app/code/core/Mage/Catalog/Model/Url.php(248): Mage_Catalog_Model_Url->refreshRewrites('4')\n#3 /var/www/html/app/code/core/Mage/Catalog/Model/Indexer/Url.php(257): Mage_Catalog_Model_Url->refreshRewrites()\n#4 /var/www/html/app/code/core/Mage/Index/Model/Process.php(212): Mage_Catalog_Model_Indexer_Url->reindexAll()\n#5 /var/www/html/app/code/core/Mage/Index/Model/Process.php(260): Mage_Index_Model_Process-> in /var/www/html/app/code/community/Loewenstark/UrlIndexer/Model/Url.php on line 87
