As I am fairly certain that this is a bug in the source code, I am not including any of the automatic information on my system which M-x report-emacs-bug produces.
Description of the bug: rmail-summary-next-msg declares its attribute
NUMBER as &optional, but does not treat it
like that, at least when called
non-interactively.
Reproducible: always
How: Calling (rmail-summary-next-msg) non-interactively.
Undesired behaviour:
Throws the following exception:
and: Wrong type argument: number-or-marker-p, nil
This is an obscure error if you have called
(rmail-summary-next-message) in accordance with the
documentation.
Explanation: This can easily be tracked to the following line in the source
code for the function, where it expects NUMBER to be non-nil:
(and (> number 0) (end-of-line)) ;; line 3 after the docstring
Line 827 in the source file in the following version of rmailsum.el:
;; Copyright (C) 1985, 1993-1996, 2000-2014 Free Software Foundation,
Workaround: Calling (rmail-summary-next-msg 1) instead of using no argument.
Best regards,
Florian v. Savigny
