Generic "Script error" being reported

[nahall]

This module looks really helpful, as I've seen evidence of some periodic javascript errors at Magento Checkout but I've not been able to reproduce them on my local machine or find out even what is being reported by the javascript console.

So I installed the module, but unfortunately the errors being reported are too generic to help. The error message reported just says "Script error.", there is nothing in Stack Trace or Error File, and Line number and Column are both 0. The only help is the URL and the fact that this confirms that I have indeed been getting a javascript error.

Do you have any ideas why it just shows "Script error."? Is there anything I can modify to get it to give me more information about where the error is occurring? Thanks!
