x = Blender.Object.getSelected()[0]

ipos = x.getIpo()

if(ipos == None):
	ipo = Blender.Ipo.New("Object", "w1z00t")
	x.link(ipo)

For some reason (ipos == None) is returning false, but x.getIpo() returns None. Anybody got any clues?

if(not ipos):

tests if ipos is none
(if there is no object named ipos an error will be generated, this is different from ipos being none)
