make-frame function on ver. 24

[B. T. Raven]

Backtrace shows an error at this position in my .emacs when used with
24.2 but not with 23.3:

(setq initial-frame-alist '((name . "arial") (top . 370) (left . 1)
(width . 205) (height . 18)))

;; this frame is created near beginning of .emacs but not named "arial."
Instead, the frame title ends up being whatever the buffername is.
Later, custom-set-faces makes the default font arial unicode.

...

(make-frame '((name . "courier")
(top . 1) (left . 1) (width . 123) (height . 18)
(visibility . icon) ; nil or icon
))

(select-frame-by-name "courier")
^
(set-frame-font "-outline-Courier
New-normal-r-normal-normal-*-*-96-96-c-*-iso10646-1")

Debugger entered--Lisp error: (error "There is no frame named `courier'")
signal(error ("There is no frame named `courier'"))
error("There is no frame named `%s'" "courier")
select-frame-by-name("courier")

..... Reading at buffer position 26164 (^ under paren)
....

Does any of you know what might be causing this? Up to this point it
looks like the .emacs has been read without a problem.

Thanks,

Ed
