2 jquery versions on page cause trouble
<p>I am working on something that is adding a jquery version to a page that already has jquery 1.2.6.</p>

<p>After loading jquery version 1.5.2 I run this:</p>

<pre><code>new_$ = jQuery.noConflict();
</code></pre>

<p>Now after page ready I run <code>new_$('.class')</code> and I get an error.</p>

<p>The problem exists only if the version of jquery is before 1.2.6</p>

<p>The error I am getting is:</p>

<p><code>Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsIDOMXPathEvaluator.evaluate]</code></p>
