"Insert/Edit link" not working after WordPress 3.5 upgrade

Hi,

I can’t edit links in the visual editor after the WordPress 3.5 upgrade. Everything else works, and I can add links manually via the Text view.

WordPress is throwing this error on click:

Uncaught TypeError: Object #<Object> has no method ‘_super’ wpdialog.min.js:1
a.widget.open wpdialog.min.js:1
(anonymous function) jquery-ui.min.js:5
v.extend.each jquery.js:1
v.fn.v.each jquery.js:1
a.fn.(anonymous function) jquery-ui.min.js:5
tinymce.create.open editor_plugin.js:1
i.(anonymous function).(anonymous function) tiny_mce.js:1

k.create.execCommand tiny_mce.js:1
i.onclick tiny_mce.js:1
(anonymous function) tiny_mce.js:1
j tiny_mce.js:1
y

Any advice? Is this a jquery conflict?
