Strange isolated jquery errors
<p>After launching a major redesign for a client, we've received a handful of emails from users who are experiencing a script that is slowing down, and eventually crashing their browsers. The errors that they send to us always point back to jquery, but I know the jquery itself shouldn't be throwing any errors.</p>

<p>I was originally using the minified version, but to better track the errors, I switched up to the development (all line breaks) version. The errors are calling one of two lines:</p>

<p>Line 1623: <a href="http://img.skitch.com/20091130-j8mp1mbjqhck1cwq49ptxstgp.jpg" rel="nofollow">A break in the Sizzle.filter function</a><br/>
Line 2317: <a href="http://img.skitch.com/20091130-xpta7eqf3bhwmj8e91371mi9r6.jpg" rel="nofollow">A inner, ending bracket on the dirCheck function</a></p>

<p>Has anyone seen these errors pop up on their own sites? The cases are isolated (I'd say less than 1 or 2% of users are having problems), but it still needs to be ironed out. FWIW: no other js scripts are throwing errors. Thanks!</p>
