	* app/gimpdrawable.c: gimp_drawable_get_color_at(): put the check
	below back but only require a non-indexed drawable if the drawable
	doesn't have an image.
	(The function may call gimp_image_get_color() with gimage == NULL
	for RGB and GRAY colors because we don't need a colormap to
	transform them to RGB space).
	This was the obscure special case (TM).
