Poor choice of words. I meant: something in emacs is calling calligraauthor.
What is that something? Find it and fix it. There is no way that that something
is built-in to emacs. Have you tried with emacs -Q?

But if it is started by emacs, emacs may be waiting for it to finish before
it continues.

I doubt that very much. This is something in your setup. Check your
.mailcap, and the variables that is used to open applications:
org-file-apps and org-file-apps-default-gnus (or -macosz or
-windowsnt, depending on your system).
