custom post types and widgets

Hi,

I used this code in my functions.php:

add_filter( 'pre_get_posts', 'query_post_type' );
  function query_post_type( $query ) {
    if( is_category() || is_tag() || is_home() && empty( $query->query_vars['suppress_filters'] ) ) {
      $query->set( 'post_type', array(
       'post', 'biografie', 'nav_menu_item' /biografie is my CPT
      ));
      return $query;
    }
  }

to display the custom post types posts in the category page of a very basic custom theme. Unfortunately, this code has a drawback, when I’m in the home page, or in the category page, the recent posts widget shows only the links to the custom post types posts and some other broken links:

the category page and the home page (index.php) has a very basic code that is:

<?php get_header(); ?>
<section>

  <?php if (have_posts()) : ?>
    <?php while (have_posts()) : the_post(); ?>
      <article <?php post_class() ?> id="post‐<?php the_ID(); ?>">
        <h1><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h1>
        Posted on: <?php the_date(); ?> at <?php the_time(); ?>
        Posted in: <?php the_category(','); ?>
        <?php the_excerpt(); ?>
        Posted by: <?php the_author(); ?>
      </article>
    <?php endwhile; ?>

    <?php next_posts_link( '&laquo; Previous Entries' ) ?>
    <?php previous_posts_link( 'Next Entries &raquo;' ) ?>

  <?php else : ?>
    <p>Not Found Sorry, but you are looking for something that isn't here.</p>
  <?php endif; ?>

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

where am I doing wrong?
