title: Generated SEO article / read-more links invalid
body: <p>I updated my old joomla 1.5 website to joomla 2.5.8. It forced me to update some modules and plugins, and I finally thought I had everything working.</p>
  
  <p>As the final step, I activated the SEO urls. Although the website and the menu still works, there are few locations where there are links generated, that don't work anymore.</p>
  
  <p>Eg: on the homepage, I have a list of articles with an intro text. These have the normal "read more" link. This link stops working when the SEO is enabled.</p>
  
  <p>It should link to:
      <a href="http://www.domain.com/home/4-nieuws/289-article-alias-test" rel="nofollow">http://www.domain.com/home/4-nieuws/289-article-alias-test</a>
  but it links to:
  <a href="http://www.domain.com/?id=289:article-alias-test" rel="nofollow">http://www.domain.com/?id=289:article-alias-test</a></p>
  
  <p>This also happens with the links below the article list, that link to other articles inside the same category.</p>
  
  <p>I traced the faulty code, and it is located in components/com_content/views/category/tmpl/blog_links.php</p>

  &lt;h3&gt;&lt;?php echo JText::_('COM_CONTENT_MORE_ARTICLES'); ?&gt;&lt;/h3&gt;
  &lt;ol&gt;
  &lt;?php
      foreach ($this-&gt;link_items as &amp;$item) :
  ?&gt;
      &lt;li&gt;
          &lt;a href="&lt;?php echo JRoute::_(ContentHelperRoute::getArticleRoute($item-&gt;slug, $item-&gt;catid)); ?&gt;"&gt;
              &lt;?php echo $item-&gt;title; ?&gt;&lt;/a&gt;
      &lt;/li&gt;
  &lt;?php endforeach; ?&gt;
  &lt;/ol&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I did not change any code in this file. Any suggestions on what might have caused this , and more importantly, how to fix it ?</p>
