Weird opera output on vbulletin

on two different sites today

I posted on two different forums that run vbulletin and the post shows this garbage:

You post something and that is the result?

Yep, tried like 4 times and that opera gibberish came out every time. Then when I would only input one word then that word actually showed. Gremlins I'm afraid. Seems like it spews 5 lines of this for every word and appends the 20% and the word to the end of every 5th line or so.

That's Opera's way of showing a JavaScript error (I think).

In vBulletin you have the option of selecting the editor you use in your Control Panel. Try selecting another WYSIWYG editor for your profile and see whether it still generates the error.

Also, what versions of vB is this happening on?
