You need to make the title attribute of the new adapter writable.  Use
something like:

  <class class=".contentitem.factory">
    <require
        permission="zope.View"
        interface="zope.app.dublincore.interfaces.IZopeDublinCore"
        />
    <require
        permission="zope.ManageContent"
        set_attributes="created modified title"
        />
  </class>
