You can try using the following definition which fixes
paragraph-indent-minor-mode to really be a minor mode as the name implies.

(define-minor-mode paragraph-indent-minor-mode
  "Minor mode for editing text, with leading spaces starting a paragraph.
In this mode, you do not need blank lines between paragraphs when the
first line of the following paragraph starts with whitespace, as with
`paragraph-indent-text-mode'.
Turning on Paragraph-Indent minor mode runs the normal hook
`paragraph-indent-text-mode-hook'."
  ;; Change the definition of a paragraph start.
  (let ((ps-re "[ \t\n\f]\\|"))
    (if (eq t (compare-strings ps-re nil nil
                               paragraph-start nil (length ps-re)))
        (if (not paragraph-indent-minor-mode)
            (set (make-local-variable 'paragraph-start)
                 (substring paragraph-start (length ps-re))))
      (if paragraph-indent-minor-mode
          (set (make-local-variable 'paragraph-start)
               (concat ps-re paragraph-start)))))
  ;; Change the indentation function.
  (if paragraph-indent-minor-mode
      (set (make-local-variable 'indent-line-function) 'indent-to-left-margin)
    (if (eq indent-line-function 'indent-to-left-margin)
        (set (make-local-variable 'indent-line-function) 'indent-region))))
