Get product's tags on category page in Magento?
===

How can I get and display product's tags on category view (in loop where products are listing)? 
I use code (from [another question][1]) and put in \app\design\frontend\\...\template\catalog\product\list.phtml:

    <?php $_tags = new Mage_Tag_Block_Product_List(); ?>

and in foreach (where products listing) display tags:

    <?php if($_tags) : ?>
        <?php foreach($_tags->getTags() as $tag):?>
            <span class="tag"><?=$tag->getName()?></span>
        <?php endforeach; ?>
    <?php endif; ?>
And it doesn't working, because this instantiate $_tags give me error: Call to a member function getItems() on a non-object in \app\code\core\Mage\Tag\Block\Product\List.php on line 45.
