Subject: bug#13066: 24.2.90; setting rmail-summary-window-size causes error
Date: Mon, 03 Dec 2012 22:43:27 +0900

When I customize rmail-summary-window-size to some integer
value (e.g. 10), M-x rmail-summary signals this error:

	Wrong type argument: stringp, nil

This is with emacs-24 branch.  This doesn't happen with
Emacs 23, but I don't remember it happens with 24.1 and 24.2.

The precise recipe:
% emacs -Q
M-x rmail RET
M-x customize-variable RET rmail-summary-window-size
;; Then set it to 10, click [apply], type q, then type h
