jquery selectors with option (select) throwing error
<p>I noticed this after a user reported the behavior since it was working fine on Chrome, Firefox and IE8+. However in IE7 the following selectors:</p>

<pre><code>$('#parentjobs option')
$('#parentjobs option:not(:contains("new"))')
</code></pre>

<p>throw this error:</p>

<pre><code>Error: Unable to get value of the property '0': object is null or undefined
</code></pre>

<p>Which points to line 5126 on jquery-1.8.3: </p>

<pre><code>context = Expr.find["ID"]( token.matches[0].replace( rbackslash, "" ), context, xml )[0];
</code></pre>

<p>I don't have IE7 installed but I can reproduce the error when I switch the document mode and browser mode to IE7 on the IE debug page (F12)</p>

<p>Any ideas what might be going wrong?</p>
