Indeed - the backtrace is as follows:

  ...
  completing-read-default("Master file: " read-file-name-internal file-exists-p t "~/src/org/" file-name-history "~/src/org/foo.org" nil)
  completing-read("Master file: " read-file-name-internal file-exists-p t "~/src/org/" file-name-history "~/src/org/foo.org")
  read-file-name-default("Master file: " nil nil t nil nil)
  read-file-name("Master file: " nil nil t nil)
  reftex-TeX-master-file()
  reftex-tie-multifile-symbols()
  reftex-access-scan-info((16))
  reftex-parse-all()
  (and (buffer-file-name) (file-exists-p (buffer-file-name)) (reftex-parse-all))
  org-mode-reftex-setup()
  run-hooks(change-major-mode-after-body-hook text-mode-hook outline-mode-hook org-mode-hook)
  apply(run-hooks (change-major-mode-after-body-hook text-mode-hook outline-mode-hook org-mode-hook))
  run-mode-hooks(org-mode-hook)
  org-mode()
  set-auto-mode-0(org-mode nil)
  set-auto-mode()
  normal-mode(t)
  after-find-file(nil t)
  find-file-noselect-1(#<buffer foo.org> "~/src/org/foo.org" nil nil "~/src/org/foo.org" (3018153 2055))
  find-file-noselect("~/src/org/foo.org" nil nil t)
  find-file("~/src/org/foo.org" t)
  call-interactively(find-file nil nil)

It's actually a bit more complicated than that: it checks if
TeX-master-file is defined as a function (i.e. AUCTEX is loaded) and if
so calls it. It then checks if tex-main-file is defined as a function
(i.e. Emacs LaTeX mode is loaded) and if so calls it. Then it check if
TeX-master is t (in which case (buffer-file-name) is called to set the
master, or 'shared (in which case it reads the file name) or non-nil (in
which case it is used verbatim) or nil (in which case it reads the file
name - the operative case here).

I'll leave it here for now: I've been sick for a couple of days and I
can't think straight right now (or ever...)
