I think I've found where the problem comes from, it has nothing to do with 
browsers or cookies (or me) AFAICT.

When manage_cutObjects() is called with REQUEST != None (i.e. when used
from the management interface) then instead of the cut objects it returns 
the value returned by manage_main(), this explains why my cb_copy_data was bad.

I've sligthly modified manage_cutObjects() to confirm that's the problem:

I've added a fourth parameter called noredirect to this method, this parameter
is a named one and defaults to 0, then at the end of this method, 
I've just done:

            if not noredirect : 
                return self.manage_main(REQUEST)
        return cp

Now it works fine both from my new management interface (Zope's modified one) 
and from python scripts, with a method which does essentially the following:

cb_copy_data = self.manage_cutObjects(ids, REQUEST, noredirect = 1)
return self.aq_parent.manage_pasteObjects(cb_copy_data, REQUEST)

In other terms manage_cutObjects() wasn't designed to be immediately followed 
by a call to another method when used from the management interface.

Not sure if this is a bug, however it seems this is a common problem in Zope
manage_xxxx() methods.

hoping this will help

bye,
