"wrong-number-of-arguments (2 . 2) 4" on creating an email

[husainaloos]

I use mu4e. Whenever I press "c" to create an email, I get the following error message:

Debugger entered--Lisp error: (wrong-number-of-arguments (2 . 2) 4)

I am not familiar with elisp enough to be able to debug it easily, but it seems that it is pointing to the line (add-hook 'completion-at-point-functions 'message-completion-function nil t) in define-derived-mode org-msg-edit-mode org-mode... line.

I use org-msg-20210916.1114 with emacs 26.3

I am noticing a similar issue when I installed org-msg.

Warning (bytecomp): Unused lexical variable ‘notmuch-show-only-matching-messages’
Warning (bytecomp): reference to free variable ‘mu4e-compose-parent-message’
Warning (bytecomp): Unused lexical variable ‘notmuch-show-only-matching-messages’
Warning (bytecomp): reference to free variable ‘mu4e-compose-complete-addresses’
Warning (bytecomp): reference to free variable ‘mu4e-compose-type’
Warning (bytecomp): assignment to free variable ‘mu4e-sent-func’
Error (bytecomp): Wrong number of arguments: (2 . 2), 4

I have mu4e v 1.6.6

I believe this issue is caused by the use of Emacs 26.3 where setq-local is limited to one variable at a time. You have two options:

1. you update to Emacs >= 27.1
2. you change the unique setq-local instruction which set both kill-buffer-hook and org-link-file-path-type variable with two setq-local instructions
