	* libgimp/gimppaletteselectbutton.c
	(gimp_palette_select_button_set_palette): check that the palette
	name actually refers to an existing palette and use the active
	palette if name is NULL or empty (like the other select buttons).

	* plug-ins/pygimp/plug-ins/palette-offset.py: use an integer value
	for a PF_INT parameter.
