i've made another fix and extended your test a bit (in  
http://svn.zope.org/?rev=91439&view=rev) to also allow the blob to be  
opened after cloning.  i ran into this problem when trying to get  
plone.app.blob to work with versioning today, but unfortunately hadn't  
updated to the latest zodb yet -- see  
http://dev.plone.org/plone/changeset/22640.

cheers,
