Can't compose message in Emacs - Notmuch

Tue Mar 24 01:57:56 PDT 2015

Greetings!

Emacs 24.4.1 (Arch Linux if that helps)
Notmuch 0.19

The problem is that I can neither compose a new email nor reply to an old
email unless I have already used  message mode (via Gnus) first.
I get an error message - Google on the error message below gets me nowhere!

Can anyone give me  pointer?

with thanks

Glyn
