Comment #7 on issue 736 by stephane...(a)gmail.com: Moose crashes when
importing Citezen (OrderedCollection(Object)>>doesNotUnderstand:
#unsafeAdd:)

I'm checking it now and I think that this is related to a bug in pharo 1.3
(related to Pool variable look up).
I will check if I load the fix if it solves the problem.
