Can org protocol capture have multiline content

Question

Not sure what's going on here. This is my capture template:

  ("j" "Capture RSS to Incoming"
   entry
   (file+headline "~/Org/jay.org" "Incoming")
   "* %c :RSS:\n%(org-link-unescape \"%i\")"
   :immediate-finish t)

When I call it with this:

(org-protocol-capture "j/aaa/bbb/cccddd")

I get what I'd expect, a line like

* [[aaa][bbb]] :RSS:
  cccddd

but when I call it with this:

(org-protocol-capture "j/aaa/bbb/ccc%0Addd")

I get the error:

byte-code: Capture abort: (end-of-file)

So somehow it seems it does not like the initial content, %i, to have multiple lines. Can anyone clue me in to what I'm doing wrong?

Multi-line content seems to be supported. Which version of emacs and org-mode are you using?

Using a recent version of emacs and org-mode, I cannot reproduce the error. invoke a clean emacs:

$ emacs -q

steps to reproduce:

(require 'org-capture)
(require 'org-protocol)

(message (emacs-version))
(org-version nil t t)

(customize-set-variable
 'org-capture-templates
 (quote (("j" "Capture RSS to Incoming"
          entry
          (file+headline "~/tmp/jay.org" "Incoming")
          "* %c :RSS:\n%(org-link-unescape \"%i\")"
          :immediate-finish t))))

(kill-new "Test headline" t)

(org-protocol-capture "j/aaa/bbb/cccddd")
(org-protocol-capture "j/aaa/bbb/ccc%0Addd")

Contents of ~/tmp/jay.org is:

* Incoming
** Test headline                                                        :RSS:
 cccddd
** Test headline                                                        :RSS:
 ccc
