Actual Results:  
Error: uncaught exception: [Exception... "Component returned failure code:

same thing happens in Mozilla/5.0 (X11; U; FreeBSD i386; en-US; rv:1.0.0)
Gecko/20020822, but searching for nsIDOMHTMLDocument.domain returned zarro
boogs... am I really the first one to report this, or did I somehow miss the
other reports?

You're getting the domain of a document which has the URL "about:blank".

This URL has no domain; not sure whether we should be throwing..

In any case, this is not JS engine -- JS has no such thing as documents or
domains; it deals with things like strings, objects, etc.

Mass-reassigning bugs.

I've just seen this problem too, what I'm doing is:

mywindow = window.open('', myname);
if (mywindow.document.domain ...

The Gecko DOM doco states that if the domain can't be determined,
document.domain should be empty.

This got fixed in bug 227263, and since then the domain for the new window is the opener's domain anyway, not about:blank.

Checked in a test for this.
