This is because bzr-svn gets first chance at probing the remote to see what
format it is in.

It sounds like bzr-svn needs to fail gracefully when EPERM happens. And just
say "NotBranch". Then the rest of the probing code can take over from there.

It should be irrelevant.

401 is Unauthorized, aka Authentication required. Maybe Vincent would have an
idea why it is failing. It should be triggering a retry.

I actually wonder if the Auth is failing, and that is causing us to fail with a
401 rather than something else.
