Magento: Script died after a certain line of code
===

I have this product called "Endless Love".
Here is the URL. http://www.eternalflowersmm.com/floral/flower-boxes/endless-love

Problem: When loading thumbnail images, the script dies. If you view source, you'll see the script ends like this.

    <a rel="lightbox[em_lightbox]" href="

This is a fracture of media.phtml. 


    <?php	foreach ($this->getGalleryImages() as $_image): ?>
    		
    			<!-- Debug -->
    			<p>
    				<pre>
    					<?php 
    						print_r($_image); 
    						echo $_image->getFile();
    						echo '<hr>';
    					?>		
    			

    	</pre>
        			</p>
        			<!-- \Debug -->
        		
                <a rel="lightbox[em_lightbox]"  
            			href="<?php echo $this->helper('catalog/image')->init($this->getProduct(), 'thumbnail', $_image->getFile()); ?>"
        //              ^--- SCRIPT DIES AT THIS POINT
            			title="<?php echo $this->htmlEscape($_image->getLabel()) ?>">
            			
            			<img src="<?php echo $this->h
    
    elper('catalog/image')->init($this->getProduct(), 'thumbnail', $_image->getFile())->keepAspectRatio(TRUE)->keepFrame(true)->resize(50,50); ?>" alt="<?php echo $this->htmlEscape($_image->getLabel()) ?>" />
        			
        			</a>
            </li>
        <?php $i++; endforeach; ?>

The script dies at this point.

    $this->helper('catalog/image')->init($this->getProduct(), 'thumbnail', $_image->getFile());

Main picture is queried this way and it works.

    <a rel="lightbox[em_lightbox]"  href="<?php echo $this->helper('catalog/image')->init($_product, 'image'); ?>"  title="<?php echo $this->htmlEscape($this->getImageLabel())?>">

This is the screen shot of admin view of that product. http://screencast.com/t/KVgvuvmE9a
These are the URLs for both images, they are accessable.

I already tried setting dev mode to true and show_erros 1 on index.php. No errors are shown up.
Checked errors.log and system.log. Nothing's there.

HELP pls.
