    Looks like the only place where uniquified-managed is set to non-nil is
    by uniquify-rationalize, so could you run with the advice below and post
    the backtrace you get with it?

        (defconst bug-36877-dup-table (make-hash-table :test 'eq))
        (defun bug-36877-debug-fix-list-dups (fix-list)
          (clrhash bug-36877-dup-table)
          (dolist (item fix-list)
            (let ((buf (uniquify-item-buffer item)))
              (if (gethash buf bug-36877-dup-table)
                  (progn (debug nil "Adding duplicate to uniquify list!" item)
                         ;; Just once.
                         (advice-remove 'uniquify-rationalize
                                        #'bug-36877-debug-fix-list-dups))
                (puthash buf item bug-36877-dup-table)))))
        (advice-add 'uniquify-rationalize :before 
#'bug-36877-debug-fix-list-dups)
