When I copy some classes and their associations from a package to another, I have the following error: org.eclipse.gmf.runtime.notation.impl.DecorationNodeImpl cannot be cast to

bug reproduced in 0.9.2 : org.eclipse.gmf.runtime.notation.impl.DecorationNodeImpl cannot be cast to org.eclipse.gmf.runtime.notation.Diagram
I cannot reproduce this on 1.0.0v201402110553 Can it be closed?
I performed the "copy" using drag & drop. We cannot do cut & paste as it is not supported yet.
Works fine in M6.
Fixed in RC1. closing
