org-capture config broken

[Orm Finnendahl <orm.finnendahl@selma.hfmdk-frankfurt.de>]

Hi,

 I use a custom script (dating back to a post from 2013) to capture my
mutt Emails using org-capture. It worked flawlessly but stopped
working some time ago (I don't exactly know, when, probably last
year).

I assume the code has changed and doesn't accept the syntax of the
org-protocol line any more.

I'm calling emacsclient with the following command:

emacsclient org-protocol:/capture:/m/mutt:YSYuf6sKfSbwtIeB@example.com/mail/%20%20Subject%3A%20test%0A%20%20%20%20From%3A%20Unknown%20%3Cdummy%40example.com%3E

It fails printing "*ERROR*: Wrong type argument: arrayp, nil" in the terminal and posts

"Greedy org protocol handler. Killing client"

in the minibuffer.

The emacsclient commmand above is generated with a perl script using
uri_escape for everything after /mail/. The single slashes in the
protocol line of the emacsclient command seem strange, but I couldn't
find any hint in the internet how the syntax is supposed to be for a
certain org-capture-template.

Maybe someone can help to debug it? Below is my init.el configuration.

Best,
Orm

        ;; ... more templates here ...
