This isn't specific to XPathExceptions, it happens for all DOM exceptions. It seems to throw when accessing the location property, which is a XPCJSStackFrame.

This just tries to access the location property of the exception, which throws 'Permission denied to create wrapper for object of class UnnamedClass'.
