If you have 2 files, A and B, and A references B. Attach B first. Then change A to reference the url for the attachment created for B. Then attach A. Also, in jsconsole you can right click and choose copy to get a complete error message. it's much better for you to do that than to hand type the message.

This behavior is standard. It's many years too late to change it. Modifying Object.prototype and using for...in carelessly are both bad ideas for this very reason. A future edition of ECMAScript will likely provide a way to define non-enumerable properties.
