I'm trying to create a plugin for wordpress that is supposed to use anything fader. I have used this plugin on other installations before without any problem. But for some strange reason, an even stranger thing happen in the WP-plugin.

The following two lines of code make Chrome stop executing JS, and FF give me some strange "visual" redirect (Don't know how to explain that better=) ).

base.$items.filter(':first').before(base.$items.filter(':last').clone().addClass('cloned'));
base.$items.filter(':last' ).after(base.$items.filter(':first').clone().addClass('cloned'));

Have someone experienced the same problem, or anything like it, and know how to solve it?

I'm using jquery v. 1.3.2
