ok, thanks Martin. Urgency over. That appears to have fixed it. So now what should I do about the missing revision stuff? How do I upgrade safely?

The command you quoted will copy backup.bzr inside .bzr. Whereas what you actually want is to move .bzr away, then mv backup.bzr to .bzr. That should get you going again, then you can file a bug for the other issue. -- Martin <<a href="http://launchpad.net/%7Embp/" target="_blank">http://launchpad.net/~mbp/</a>> </blockquote></div>
