Caption breaks page

With the first image I added, the caption worked fine.

the second post to contain a captioned image didn’t fare as well.

<div class="single">

		  <?php if (strlen($videocode) > 1 && $videolocation == 'In the middle column') {

            if ($videocode && $AE->parseUrl($videocode)) {
                $AE->setParam('wmode','transparent');
                $AE->setParam('autoplay','false');
                $AE->setHeight(370);
                $AE->setWidth(570);
                echo'<div class="zoomVideo">';
                echo $AE->getEmbedCode();
                echo'</div>';
                }
            } ?>

       		  <h1><?php the_title(); ?></h1>

          	  <div class="entry">
			  <?php include "includes/display_metadata.php"; ?>

 			  <?php the_content(); ?>

		  	  </div>

		  	  <br clear=all>
		  	  <div style="clear:both"></div>

          	<?php wp_link_pages(array('before' => '<p class="pages"><strong>Pages:</strong> ', 'after' => '</p>', 'next_or_number' => 'number')); ?>

        </div><!-- end .single -->

        <div class="cleaner">&nbsp;</div>

Everything else on the site works fine, including galleries, video embeds, etc. I can’t find an open tag or anything. It’s interesting to note that the breakage seems to be placing an auto-generated excerpt from the content into the header.

I did see a support ticket from 7 days ago where wordpress folk are saying something is up with captions, but not sure if this is related.
