I bet you are trying to list the reviews in the product list page.
in case I'm right, it doesn't work like you are doing it. You cannot use Mage_Review_Block_Product_View_List for showing reviews in the product list page.
That block needs to be in a "one single product context" (aka Product page) because it expects Mage::registry('product') to return a valid product model instance.

The solution in your case would be:

  1. Remove the reviews from the product listing page
  2. Use an other block that extends Mage_Review_Block_Product_View_List but with a different getProductId method. Something like this (untested):

    public function getProductId()
        if ($this->getProduct()) {
             return $this->getProduct()->getId();
        return parent::getProductId();

now you can get the reviews in the list page like this:

<?php $reviewBlock = Mage::app()->getLayout()->createBlock('[module]/block_alias_here')->setProduct($_product);?>
<?php //do your magic with $reviewBlock?>

where $_product is the current iteration from the product list to be shown.
