while using:
PyQt-x11-gpl-4.5-snapshot-20090304
on:
Python 2.5.2 (r252:60911, Jul 31 2008, 17:28:52)

If I don't keep a persistent reference to a spacer Item I get a
segfault. This is a new event since upgrading from 4.4 to 4.5. I've
attached the code, and one thing that is peculiar is that I just need
'a' reference to a spacer item.
so should I keep a reference to spacer items?
