Capture template stopped working: nil

[Florian Lindner <mailinglists@xgm.de>]

Hello,

since recently, one of my capture templates stopped working. Message is:

Template key:
org-capture: Capture template ‘j’: nil

and:

- %?

is added to journal.org. I have also tried some other template text like "foo" (without any keys), but the message is the same.

value of org-capture-templates is:

 (("t" "Todo" entry
  (file+headline "" "Tasks")
  "* TODO %?\n%t\n%i")
 ("q" "Question" entry
  (file+headline "" "Questions")
  "* %?\n%t\n%i")
 ("c" "Code Question" entry
  (file+headline "" "Code Questions")
  "* %?\n%t %F\n%i")
 ("j" "Journal" item
  (file+datetree
   (concat org-directory "/journal.org"))
  "%?\n%i" :kill-buffer t)
 ("m" "Mail" entry
  (file+headline "" "Mail")
  "* TODO %? %a\nSCHEDULED: %(org-insert-time-stamp (org-read-date nil t \"+0d\"))\nFrom: %:from")
 ("h" "CSC Todo" entry
  (file+headline "~/Dropbox/CSC/CSC.org" "TODOs")
  "* TODO %?\n%t\n%i"))


All templates are working just fine, only the Journal one not.

Org mode version 9.0.9 (9.0.9-elpa @ /home/florian/.emacs.d/elpa/org-20170622/)

Any idea anyone?

Thanks!
Florian
