Thierry, try adding the following to zc.catalog's configure.zcml  
(this is for all four of the zope.app.catalog-aware indexes).

   <content class=".catalogindex.ValueIndex">
     <require
         permission="zope.ManageServices"
         interface="zope.app.catalog.interfaces.IAttributeIndex
                    zope.index.interfaces.IStatistics
                   "
         set_schema="zope.app.catalog.interfaces.IAttributeIndex"
         />
   </content>

   <content class=".catalogindex.SetIndex">
     <require
         permission="zope.ManageServices"
         interface="zope.app.catalog.interfaces.IAttributeIndex
                    zope.index.interfaces.IStatistics
                   "
         set_schema="zope.app.catalog.interfaces.IAttributeIndex"
         />
   </content>

   <content class=".catalogindex.DateTimeValueIndex">
     <require
         permission="zope.ManageServices"
         interface="zope.app.catalog.interfaces.IAttributeIndex
                    zope.index.interfaces.IStatistics
                   "
         set_schema="zope.app.catalog.interfaces.IAttributeIndex"
         />
   </content>

   <content class=".catalogindex.DateTimeSetIndex">
     <require
         permission="zope.ManageServices"
         interface="zope.app.catalog.interfaces.IAttributeIndex
                    zope.index.interfaces.IStatistics
                   "
         set_schema="zope.app.catalog.interfaces.IAttributeIndex"
         />
   </content>


Then give it a try.  (This only works if you are using the indexes I  
listed, but you probably get the idea.)  If this helps, we should  
check it in.
