Possible jQuery issue in IE

Possible jQuery issue in IE

Hey everyone,
Only in IE, I'm getting this error:

Webpage error details

User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0)
Timestamp: Thu, 3 Mar 2011 15:55:34 UTC


Message: Invalid argument.
Line: 16
Char: 63945
Code: 0
URI: https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js



Not sure if that gives anyone enough knowledge about what could be the issue, but any insight on where I should look would be greatly appreciated. Thanks!
