There's something I really do not understand in this bt.

This is (substring x (match-end 3))
So the string `x' is well, the entry about St. Patrick.

Where the this is coming from ?
The code is:

#+begin_src emacs-lisp
	    (setq x (concat (substring x 0 (match-end 1))
			    (format org-agenda-todo-keyword-format
				    (match-string 2 x))
			  (org-add-props " " (text-properties-at 0 x))
			  (substring x (match-end 3)))))
#+end_src

How the " " used as first arg of `org-add-props' can have so much
properties, like a todo-state set to "STARTED" and even a org-marker set
to a position in the uni.org file set? It's an empty string for Emacs's
sake.

What's even more troubling is that this code is executed only if `re' is
not nil:

#+begin_src emacs-lisp
(setq re (get-text-property 0 'org-todo-regexp x))
	(when (and re
…))
#+end_src

How `re' cannot be nil since there's no org-todo-regexp in `x' (the
entry about St. Patrick.

Tassilo, if you can reproduce the backtrace, could you take a look at
the value of `re', `x' and `pl'? Maybe it can help, I'm a bit lost right
now.
