Yes, 15.5 (image-size returns (38.57142857142857 . 15.5)), which means
the decremented frame-height should be > 34.5, so 34 is too small.  This
is with the font
-unknown-DejaVu Sans Mono-normal-normal-normal-*-12-*-*-*-m-0-iso10646-1,
which I've been using since well before the fancy splash image started
failing to be displayed.
