Comment #7 on issue 736 by stephane...@gmail.com: Moose crashes when importing Citezen (OrderedCollection(Object)>>doesNotUnderstand: #unsafeAdd:) http://code.google.com/p/moose-technology/issues/detail?id=736
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.
