Comment 3 for bug 226303

As explained in https://bugs.edge.launchpad.net/bzr/+bug/129307/comments/2, the server lies.

Instead of returning a 404 *error* code, it redirects the request to another page.

This has deep implications in the code base and seems like a significant amount of work to design a work around.

But if you want to provide a patch, I'll do my best to help you there.
