Latest post shows twice

My last blog post shows twice (as post number one and two) and I can’t figure out why. Here’s my index.php

<?php get_header(); ?>
	<div id="content">

<?php if ( is_home() ) {
query_posts($query_string . '&cat=-2');
}
?>

	<?php if (have_posts()) : ?>

<?php while (have_posts()) : the_post(); ?>

			<div class="post" id="post-<?php the_ID(); ?>">
				<h1><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></h1>
								<p class="postmetadata">I
	  <?php the_category(', ') ?> | <?php edit_post_link('Edit', '', ' | '); ?>  <?php the_time('l, F jS, Y') ?> | <?php comments_popup_link('0 Kommentarer »', '1 Kommentar »', '% Kommentarer »'); ?> | <?php if(function_exists('wp_print')) { print_link(); } ?> | <a href="<?php trackback_url(true); ?> " rel="trackback">Trackback</a></p> 

							<span style="display:none;"><?php todays_overall_count($post->ID, '', '', '', '0'); ?></p></span>
				                <div class="entrytext">
					<?php the_content('Fortsätt läsa artikeln &raquo;'); ?>
				</div>

		</div>

		<?php endwhile; ?>

		<div class="navigation">
			<div class="alignleft"><?php next_posts_link('Äldre inslag') ?></div>
			<div class="alignright"><?php previous_posts_link('Nyare inslag') ?></div>
		</div>

	<?php else : ?>

		<h2 class="center">Vi hittar inte det du söker.</h2>
		<p class="center">Vi hittar ingen matchning till den söktermen. Prova något annat.</p>
		<?php include (TEMPLATEPATH . "/searchform.php"); ?>

	<?php endif; ?>

	</div>
<?php get_sidebar(); ?>
<?php get_footer(); ?>

Has anyone experienced a similar problem and found a solution?
