This shouldn't happen in master branch.

There is a function in ORG-NEWS that will repair old documents, but it
will _not_ merge duplicate properties drawers.

This should find such entries.

  (org-element-map (org-element-parse-buffer 'element) 'headline
    (lambda (h)
      (and (org-element-map h 'drawer
             (lambda (d) (equal (org-element-property :name d) "PROPERTIES"))
             nil t 'headline)
           (let ((begin (org-element-property :begin h)))
             (message "Entry with erroneous properties drawer at %d" begin)
             begin))))
