As I said before, there is much that eludes me in 
'org-refile-get-location', but I'm trying to pin this down further by 
getting some inspection points and trying at least to grasp where it 
happens.

In particular, I set one inspection point exactly after the 
completing-read function is called to store the value of local variable 
"answ" which is the return value of the completing-read function. That 
is, right after:

#+begin_src emacs-lisp
(setq answ (funcall cfunc prompt tbl nil (not new-nodes)
                        nil 'org-refile-history
			(or cdef (concat (car org-refile-history) 
			extra))))
#+end_src

The value of "answ" right after this step is then:
- with 'ivy-mode' off, that is with 'completing-read-default' as 
 'completing-read-function': "test.org/Top heading 1//" (that is with a 
 *double trailing slash*).
- with 'ivy-mode' on, that is with 'ivy-completing-read' as 
 'completing-read-function': "test.org/Top heading 2/"

In both cases the last trailing slash seems (as far as I understand it) 
to be then trimmed off by 'org-refile--get-location' with:

#+begin_src emacs-lisp
(replace-regexp-in-string "/$" "" refloc)
#+end_src

Why 'ivy-completing-read' does not return the end double slash while 
'completing-read-default' does, I have no idea. But the fact that 
'completing-read-default' returns the refile location with a double 
trailing slash makes me think there is still something to be fixed in 
'org-refile-get-location'.

Best,
Gustavo.
