open /Applications/Emacs.app --args -q
the emacs icon on the fancy splash screen (*GNU Emacs*) is missing, try to
increase the frame size a little bit then press `c-h c-a', the icon is back,
however if decrease the frame size to some size less or equal to the initial
startup size and press `c-h c-a' the icon is lost again.

I don't think this is a bug, and AFAIK it has been like this for some time.
The image is not shown if the frame seems to be too small.
See use-fancy-splash-screens-p.

OK, I see.
Though use-fancy-splash-screens-p is not strictly correct on this.
If I force it to use splash screen:
(defun use-fancy-splash-screens-p () t)
And examine these values of the splash screen on the initial startup
frame:
(window-pixel-height)
=> 476
(cdr (window-text-pixel-size
(selected-window) nil nil nil nil t)) ; include mode-line
=> 462
it has plenty room for display.

How do you deduce that this is enough? splash.xpm needs 217 pixels on
my system, and use-fancy-splash-screens-p reserves 19 more lines for
text, which on my system need 19 x 16 = 304 more pixels. The sum is
greater than either 462 or 476, so it sounds to me like
use-fancy-splash-screens-p is right. (On my system, the window is 528
pixel high, which is indeed greater than 217 + 304.)

I can see that on my system the splash screen fits the frame quite well
in one page.
window-text-pixel-size (462) above returns the height of the text
displayed,
that counts the height of the splash image and the window-pixel-height
is 476 > 462, both inludes the height of the modeline.

Which splash file on your system is actually used for display?
The problem is that use-fancy-splash-screens-p uses splash.xpm to
determine the image height which is 217 pixel high, while on my system
splash.png (188 pixel high) is actually used (since it's more fancier
than the xpm one).
I think it's better for use-fancy-splash-screens-p and fancy-splash-head
to use the same file:

Ah, that was important information. Yes, I guess
use-fancy-splash-screens-p should do the same as fancy-splash-head to
determine which image will be displayed.

Thank, applied.
The whitespace in your patch was severely messed up, to the extent of
extra blank lines all over the place. Please try to figure out why that
happened to avoid it in future.
This raises the question of why some of the versions of the splash image
have slightly different appearance / image dimensions.
png and svg are (almost) the same, as are pbm and xpm.
I did "convert -background transparent splash.png splash2.xpm", and the
result looked better to my untrained eye than the current splash.xpm
does, apart from some edge effects.
Perhaps someone would like to try re-making the xpm and pbm versions
so that they are closer to the other versions.

Sorry for that. Most of the time I just use Gnus, I used gmail web
interface once and it just screwed me up.
