The problem appears to be in the remote repository. It seems like there
 is a symbolic link in the last revision now 
that points at an empty file, and this causes bzr to break. I'm
wondering what the best approach is here. It would be nice if bzr could
just print a warning in this situation and simply not create the
symbolic link in the working tree.

The easiest way to deal with this particular instance of the problem is
to have the unison folks remove the symlink from their tip revision. 

Can you also file a bug about this?

Cheers,

Jelmer
