Confirmed. The culprit seems to be some not-so-robust code in
org-agenda-highlight-todo. Here's the code:
--8<---------------cut here---------------start------------->8---
...
(let ((pl (text-property-any 0 (length x) 'org-heading t x)))
(setq re (get-text-property 0 'org-todo-regexp x))
(when (and re
(equal (string-match (concat "\\(\\.*\\)" re "\\( +\\)")
x (or pl 0)) pl))
(add-text-properties
(or (match-end 1) (match-end 0)) (match-end 0)
(list 'face (org-get-todo-face (match-string 2 x)))
x)
(when (match-end 1)
(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)))))))
...
--8<---------------cut here---------------end--------------->8---
The problem is that pl is nil in this case and so is the
value of
(string-match (concat "\\(\\.*\\)" re "\\( +\\)") x (or pl 0))
but they compare equal, so the body of the
(when (and re ...)
<body>
)
is evaluated with disastrous results: the string-match has failed so it
has not set any matches for (match-end ...) to find. In this case,
(match-end 1) evaluated to 36 (that's in a 3-character string :-).
AFAICT, the whole body should be skipped in the case when pl is nil:
(let ((pl ...))
(when pl
(setq re (...)
(when (and re (...))
...
...))))
But it's not clear to me whether this is the only bug.
