Call to getOwnPropertyDescriptor() fails with NS_ERROR_XPC_BAD_CONVERT_JS

Reproducible: Always

Steps to Reproduce:
Execute From Javascript:

Object.getOwnPropertyDescriptor(Element.prototype, "textContent");

Actual Results:  
uncaught exception: [Exception... "Could not convert JavaScript argument" nsresult: "0x80570009 (NS_ERROR_XPC_BAD_CONVERT_JS)" location: <TOP_LEVEL> :: line 4" data: no]

Expected Results:  
Should return the property descriptor (does if you de-reference Element.prototype in Firebug and open the object)

This occurs in FireFox 4.0b8, getOwnPropertyDescriptor() which I believe is new to FF 4.0
