title: qTranslate plugin switching language in the same page
body: <p>I have a serious problem with a qTranslate buttons.<br>
  Right now the web structure is: <code>http://www.site.com/news/?lang=en</code></p>
  
  <p>When I stay in the home page and I try to change the language, the botton opens the first post (maybe because I'm using permalink):</p>
  
  <pre><code>&lt;?php if(qtrans_getLanguage()=='it'): ?&gt;
      &lt;li&gt;&lt;a href="&lt;?php echo qtrans_convertURL(get_permalink(), 'en'); ?&gt;" &gt;eng&lt;/a&gt;&lt;/li&gt;
      &lt;li class="liguaattiva"&gt;ita&lt;/li&gt;
  &lt;?php endif; ?&gt;
  &lt;?php if(qtrans_getLanguage()=='en'): ?&gt;
      &lt;li class="liguaattiva"&gt;eng&lt;/li&gt;
      &lt;li&gt;&lt;a href="&lt;?php echo qtrans_convertURL(get_permalink(), 'it'); ?&gt;" &gt;ita&lt;/a&gt;&lt;/li&gt;
  &lt;?php endif; ?&gt;
  </code></pre>
  
  <p>How to solve this without open the last post or come back at the home page, but only switching language in the same page?</p>
