Comment #12 on issue 736 by usman.bh...@gmail.com: Moose crashes when importing Citezen (OrderedCollection(Object)>>doesNotUnderstand: #unsafeAdd:) http://code.google.com/p/moose-technology/issues/detail?id=736
The problem seems to be resolved now. The import of Citezen (all packages) now works in Moose.
