1. Create a mailbox file containing one message. (I believe that any
mailbox file (containing at least one message) will suffice.)
2. Execute (setq rmail-nonignored-headers nil).
This has the defined meaning that there are no "nonignored" headers that
are displayed even if they match rmail-ignored-headers:
rmail-nonignored-headers is a variable defined in `rmail.el'.
Its value is "^x-spam-status:"
Documentation:
Regexp to match X header fields that Rmail should show.
This regexp overrides `rmail-ignored-headers'; if both this regexp
and that one match a certain header field, Rmail shows the field.
If this is nil, ignore all header fields in `rmail-ignored-headers'.
3. Run Rmail on the mailbox file: C-u M-x rmail RET ...file-name... RET.
4. An error message is displayed in the minibuffer. As it is recorded
in the *Messages* buffer:
rmail-copy-headers: Wrong type argument: stringp, nil
5. Setting debug-on-error to t before step 3 will give a traceback
showing that rmail-copy-headers has used the value of
rmail-nonignored-headers as an argument to looking-at without first
checking whether the value of rmail-nonignored-headers is non-nil.
