Error in template – ‘null’ or not an object?

Hi,

I’ve made a new template for pages that I don’t wish to have a sidebar on.

It works and everything but I get the following error:

Line: 23
Char: 3

‘null’ is null or not an object.

The code is as follows:

<?php
/*
Template Name: Sidebarless
*/
?>

<?php get_header(); ?>

<div class="content">
	<div id="viewingfigsnomos">
		<div id="current-content">
			<div id="primarycontent" class="hfeed">

				<?php while (have_posts()) { the_post(); ?>
				<div id="post-<?php the_ID(); ?>" class="<?php k2_post_class(); ?>">

					<div class="page-head">
						<h2><a href="<?php the_permalink() ?>" rel="bookmark" title='<?php printf( __('Permanent Link to "%s"','k2_domain'), wp_specialchars(strip_tags(the_title('', '', false)),1) ); ?>'><?php the_title(); ?></a></h2>
						<?php edit_post_link(__('Edit','k2_domain'), '<span class="entry-edit">','</span>'); ?>
					</div>

					<div class="entry-content">
						<?php the_content(); ?>

						<?php link_pages('<p><strong>'.__('Pages:','k2_domain').'</strong> ', '</p>', 'number'); ?>
					</div>

				</div> <!-- #post-ID -->
				<?php } // End the Loop ?>

			</div> <!-- #primarycontent .hfeed -->
		</div> <!-- #current-content -->

		<div id="dynamic-content"></div>
	</div> <!-- #primary -->
	</div> <!-- .content -->

<?php get_footer(); ?>

Any ideas how I can remove this curséd error?
