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,
