Hello,

As mentioned in a previous mail, there seems to be
a very serious bug with Export/Import and inheritance.

Practically what happen is that when a class inherits
from another class that belongs to another product,
its exportation also include the class that it inherits.
(have a look at the exported xml file to see the problem).

Practically later after re-importing this class, its subclass
is not the one that you see in your Zope browser, but rather
a kind of "Ghost" class.

Perhaps this apply also to your property inheritance bug
to a certain extent ?
(for instance, you may have had exported/imported when you
had to upgrad your Zope installation).
