I've just e-mailed a respons to your error report through our website, but I'll put some information about it here:
Most likely it has to do with the loaded Superfish component/plugin. This is a known issue which cannot be resolved by us. It seems there's coding needed in Superfish for it.
Always try to find out how many installed components/plugins are using jQuery. Different versions are most likely the cause of conflicts between components.
If you need more help, please reply to our e-mail.
