Comment:
It seems that the icon being used is /usr/share/pixmaps/nautilus.xpm,
which is 32x23 (and looks dreadful anyway). I think icons are supposed
to be 48x48 for the splash screen, aren't they?

/usr/share/pixmaps/nautilus/nautilus-launch-icon.png seems better,
although the nautilus shell icon isn't really needed at all (just the
file browser icon, if anything).
