[O] Bug: master: "Capture abort: (error Format specifier doesn’t match argument type)"

[Gregor Zattler]

Hi org-mode developers,

with

GNU Emacs 26.0.91 (build 2, x86_64-pc-linux-gnu, GTK+ Version
3.22.11) of 2018-04-02

and 

Org mode version 9.1.9 (release_9.1.9-560-gf93aa7 @
/home/grfz/src/org-mode/lisp/)


I get

"Capture abort: (error Format specifier doesn’t match argument
type)"

after hitting the template key in order to capture something.

This is not the case in

Org mode version 9.1.9 (release_9.1.9-3-gb1a639 @
/home/grfz/src/org-mode/lisp/)
from maint as of b1a6395dfeadd9adc5ce7633f341dfbbb30bd39e.


I tried to bisect this with
make autoloads ; emacs-snapshot -nw --debug-init --eval '(org-capture 4 "t")'
as a test, but did not find the culprit.

As a workaround I switched to main.

Thanks for your attention, Gregor
