I does it for me and should do the trick. I tracked down the problem
to `org-copy-subtree' not beeing able to correctly determine the end
of the subtree to copy.

The problem is here:

,----
|     (setq beg (point))
|     (skip-chars-forward " \t\r\n")
|     (save-match-data
|       (save-excursion (outline-end-of-heading)
|                     (setq folded (outline-invisible-p)))
|       (condition-case nil
|         (org-forward-same-level (1- n) t)
|       (error nil))
|       (org-end-of-subtree t t))
|     (org-back-over-empty-lines)
`----

(org-end-of-subtree t t) moves point to either 1/ the beginning of the
following sibling, 2/ the beginning of the last empty line in buffer
if it is present, or 3/ to the end of the last line if an last empty
line is missing.

3/ is the edge-case in question. 1/ and 2/ work with the assumption
that point is /not/ inside the entry if back-over-empty-lines is
called. Thus

(forward-line -1)
(beginning-of-line 2)

for 1/ and 2/ means: Stay where you are. For 3/ it doesn't. For 3/ it
moves point to the beginning of the last line in buffer, i.e. in front
of the last line of content in the entry.

Best,
