I had the same issue, only it is with other plugins on my site. Seems to function fine by ignoring the errors in firefox, but IE pukes all over itself.

I have not yet even looked into the problem, but figured I would report it as well. Could be that I use no-conflict rules in js, but who knows. Hope to have an answer to this figured out in the next few days.
