When I run `emacs --debug-init', no error is detected and emacs starts
without executing the most of my .emacs. By trying to comment out
various parts of my (huge) .emacs, I figured out that commenting the
following line prevents the error. The line in question is:
(setq notmuch-wash-original-regexp "^\\(--+\s?\\([oO]riginal
[mM]essage\\|Messaggio Originale\\)\s?--+\s*\\|\s*_____*\s*\n\n\\(Da:\\|Von:\\)
.*\\)$"
The interesting thing is that this line has nothing to do with org-mode.
It configures behavior of the notmuch email client.
Does anybody know how to allow having the above line in my .emacs?
