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 Debugger entered--Lisp error: (error "Variable binding depth exceeds max-specpdl-size") mapcar(#[(item) "\301\302@\"AB\207" [item format "%s"] 3] ((From .
