OBJECT's (text/html) data doesn't pass callbacks for prompting

I just crashed due to http://www.w3.org/Style/Group/members.html , which has an
<object type="text/html"/> whose data requires HTTP authentication.  The
mCallbacks on the HTTP channel were null.

I filed bug 199910 on the fact that HTTP crashes rather than asserting or
failing somewhat more gracefully.

However, even if that's fixed, this would still mean that there would be no
prompt, but just an error.  The content/layout code that does the loading needs
to pass the right prompt callbacks.

Is this a recent regression? My debug build isn't crashing. Can you attach a
