org-agenda-get-todos loops trying to match the text in the file against a 
regexp:

So the match was not able to provide a non-nil (match-end 2), probably
because of a headline missing some essential ingredient, perhaps,
maybe. Check the emacs.org file carefully. If you run it again, when it
bombs out, you can examine variables with ``e'' and perhaps get a better
idea of where the suspect headline might be.

Another way to debug it is to save a backup of your emacs.org file and
then systematically cut it down by keeping (roughly) the half that
produces the error until you've narrowed it down to the headline that
causes the error.

I'd say probably not.
