The repository is the Unison project at
https://webdav.seas.upenn.edu/svn/unison/trunk

I have a branch I created long ago that updates quite happily.  Also
there is a branch on Launchpad which seems OK but I am not sure how it
gets updated from the Subversion repository -- and it is a few days out
of date.

The problem is in trying to create a new branch.  I have tried both as a
branch, a bound branch, and a checkout (*) both standalone and in a
shared repository and always the same outcome.  Which is indicative that
the problem is not really to do with the Bazaar infrastructure.  Also
the data indicates the problem is to do with a Subversion commit post
creation of the two branches that work.  Either that or Bazaar or
bzr-svn has changed in a significant way since then.

Clearly the problem is with a symlink -- the message says so :-)

I guess what has thrown me is that the branch creation has happened the
problem only exhibits itself when trying to create the working tree.

Also I can't quite believe the Unison guys have versioned a symlink --
this project explicitly has to built and run on Windows as well as
Linux, Solaris, Mac OS X, Free BSD, Unix, any operating system for which
there is an OCaml port.

I don't have write permission to this repository so I cannot fix
anything myself.

I am happy to do more experimentation, but I would need some direction
so as to avoid floundering uselessly.

Thanks.

(*) I now realise that I really don't have much of a clue what the
differences are between "bound branch" and "heavyweight checkout" so I
tried both.  I guess I should have tried "lightweight checkout" but
haven't as yet.
