append_branch() is not needed anymore (for couple of releases, actually, 
being added in one of the 3.x releases), but should be harmless unless 
you do other changes of r-uri/dst-uri after append_branch(). Can you try 
without append branch?

Also, can you look at config execution trace to be sure append branch is 
not called twice somehow?
