[Zope] Openflow product is broken on ZMI

[Riccardo Lemmi]

Try to import the zexp in another folder on the server you done the export. If
the import goes correct the problem is in the other server (see below),
otherwise there is some incompatibilities due to the obsolete code.

The "Could not import class" message seems to suggest that OpenFlow is not
installed on this server (or maybe there is a permissions problem).
