capture template for .ics invitation in vm

[<prayner@unimelb.edu.au>]

In reality probably an embarrassing emacs-lisp error on my part.

I'm trying to make a capture template for turning the very frequent
invitations I get in .ics format (I think) into org agenda items.
The basis is the ical2org awk script maintained by Eric Fraga.
My template is defined as follows:
("i" "invite" entry (file+headline "~/.org/todo.org" "Tasks")
	 "* TODO %(org-capture-vm-invite)\n" :immediate-finish t)

And org-capture-vm-invite is defined as

(defun org-capture-vm-invite ()
  (interactive)
  (with-temp-buffer
    (insert-buffer (org-capture-get :original-buffer 1))
    (shell-command-on-region (point-min) (point-max) "ical2org" nil t)
    (buffer-substring-no-properties (point-min) (point-max))))

A problem seems to be the line
    (insert-buffer (org-capture-get :original-buffer 1))
since :original-buffer doesn't seem to be defined in
org-capture-plist. I've verified that by printing it.
It's likely I'm going about this completely the wrong way so does
anyone have the right way to get information from the buffer where
capture was called during an embedded sexp?
Please reply directly as well as to the list since I'm a loong way
behind on reading.
Thanks in advance
Peter
