bug#73250: 29.4; org-refile-get-targets wrong-type-argument

[Serghei Iakovlev]

Hello,

I encountered an issue with `org-mode' in my Emacs configuration
related to periodic clearing of the refile cache during idle time.  I
am using the following code snippet, which runs during idle time to
clear the cache of refile targets:

--8<---------------cut here---------------start------------->8---
(run-with-idle-timer 600 t (lambda ()
                             (require 'org-refile)
                             (org-refile-cache-clear)
                             (org-refile-get-targets)))
--8<---------------cut here---------------end--------------->8---

As far as I can tell, the code is syntactically and semantically
correct.  However, it doesn't seem to work as expected and triggers
an error.  After enabling `toggle-debug-on-error', I found the
following error message in the morning:

--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  looking-at(nil)
  org-refile-get-targets()
  (closure (t) nil (require 'org-refile) (org-refile-cache-clear) (org-refile-get-targets))()
  apply((closure (t) nil (require 'org-refile) (org-refile-cache-clear) (org-refile-get-targets)) nil)
  timer-event-handler([t 0 600 0 t (closure (t) nil (require 'org-refile) (org-refile-cache-clear) (org-refile-get-targets)) nil idle 0 nil])
--8<---------------cut here---------------end--------------->8---

However, when I manually execute the `org-refile-get-targets' function,
it works without any issues.  Unfortunately, I cannot provide a more
reproducible scenario beyond what I've described here.

For further investigation, I am attaching links to my complete Emacs
configuration in the hope that it might help.  These are permalinks
to the specific commit reflecting the state of my configuration at
the time of the error:

Thanks, but please report this to the Org developers first.  Org has
its own list for reporting bugs.  If the Org developers arrive at the
conclusion that it's a core Emacs bug, please come back here with the
details.
