I am currently having difficulty debugging an error that I have encountered.
Please see the bottom of this message for further information about my
system and init files.

Problem:

When I have nxhtml loaded, via my init file, I cannot get my .org files to
open in org-mode. I have set my init file up for org-mode according to
Section 1 of the org-mode manual.

 I have the following message in

*Backtrace*:

--begin *Backtrace*--
Debugger entered--Lisp error:  (error ":END: line missing at position
111725")
  signal(error (":END: line missing at position 111725"))

  error(":END: line missing at position %s" 111725)

mode))

  find-file-noselect("~/Documents/Personal.org" nil nil t)

  find-file("~/Documents/Personal.org" t)

  call-interactively(find-file)
--end *Backtrace* --

However, if after receiving this message, I enter "M-x org-mode" and start
org-mode, and load the file again (Personal.org), it loads in org-mode with
no problems. If I disable nxhtml from autoloading, I have no problem opening
Personal.org automatically in org-mode.

I believe that the call

mumamo-ad-set-auto-mode-0(org-mode nil)

in *Backtrace* is probably the culprit. There seems to be an issue with a
missing ":END:" line, but I do not know which file this missing :END: is in
as the I can not deduce from the *Backtrace* which file it is missing from.

Questions:

1) How can disable mumamo from handling org-mode? Org-mode does a fine job
of recognizing my .org files on its own.

2) Does anyone know which file the missing :END: is in ? How can I get the
lisp debugger to give me more information about where the file with the
missing :END: is? (yes, I did a C-u M-x org-reload RET and I have the same
*Backtrace* message)

My system:

Aquamacs is a distribution of GNU Emacs that is adapted for Mac users.

on my Mac OS X 10.6.7.

Note: I have the exact same error when running emacs22 from the command-line
from terminal.
