title: wp_get_archives, one post missing
body: <p>i'm trying to built a custom archive page.</p>
  
  <p>there is a dropdownmenu for the year, whichs displays the post count (correctly). but when i pick one year, one post (the newest) is missing. </p>
  
  <p>this is my dropdown</p>
  
  <pre><code>&lt;select name="archive-dropdown" onChange='document.location.href=this.options[this.selectedIndex].value;'&gt; 
  &lt;option value=""&gt;&lt;?php echo esc_attr( __( 'Jahr' ) ); ?&gt;&lt;/option&gt; 
  &lt;?php wp_get_archives( array( 'type' =&gt; 'yearly', 'format' =&gt; 'option', 'show_post_count' =&gt; 1 ) ); ?&gt; 
  </code></pre>
  
  <p>and there is my loop</p>
  
  <pre><code>&lt;?php while(have_posts()) : the_post(); ?&gt;
    &lt;div &lt;?php post_class('post-programm'); ?&gt;&gt;
      &lt;a href="&lt;?php the_permalink(); ?&gt;"&gt;
        &lt;div class="entry-content"&gt;
          &lt;h3&gt;&lt;?php the_title(); ?&gt;&lt;/h3&gt;
        &lt;/div&gt;
      &lt;/a&gt;
    &lt;/div&gt;
  &lt;?php endwhile; ?&gt;
  </code></pre>
  
  <p>i also tried a query_posts, but in this case i get all the posts, not only for one particular year.</p>
  
  <pre><code>&lt;?php query_posts('posts_per_page=-1');
          if(have_posts()) : while(have_posts()) : the_post(); ?&gt;
  </code></pre>
  
  <p>thanks in advance for any help!</p>
