All bugs which are under the directory mozilla-1.0/ link to nonexistent pages (404s). These pages currently link to pages and scripts which are not in the mozilla-1.0/ directory but one directory up in the structure, such as bug_status.html, show_bug.cgi, showdependencytree.cgi, and showdependencygraph.cgi.

As I cannot figure out what this report is talking about or what refers to the given links, I am resolving this as invalid.
Apparently the bugzilla.mozilla.org/mozilla-1.0 subtree, which probably didn't serve any purpose after 1.0 was released, was deleted sometime mid-to-late 2002. I'd forgotten by then that I'd filed this bug.
