Comment #9 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 checked and loading 4899 does not help but the problem is really linked with the use of Pool Variable. I will have a look.
