	* app/core/gimplayer.c (gimp_layer_add_mask): g_return_if_fail()
	on the mask's image being the same as the layer's image. The PDB
	already checks for this.

	* app/core/gimpimage.c (gimp_image_add_layer,channel,vectors):
	remove calls to gimp_item_set_image() because we only accept
	itmes of this image anyway.
