Intids missing adapter declarations?

Hi,

I had to add this to my configure.zcml file to get IntIds running:

 <adapter
     for="persistent.interfaces.IPersistent"
     provides="zope.app.keyreference.interfaces.IKeyReference"
     factory="zope.app.keyreference.persistent.KeyReferenceToPersistent"
     trusted="y"
 />

 <class class="zope.app.keyreference.persistent.KeyReferenceToPersistent">
    <require permission="zope.Public"
             interface="zope.app.keyreference.interfaces.IKeyReference" />
 </class>

 <adapter
     for="persistent.interfaces.IPersistent"
     provides="ZODB.interfaces.IConnection"
     factory="zope.app.keyreference.persistent.connectionOfPersistent"
 />

Otherwise I'd get:

 File 
"/home/jmo/philikon-local-components/lib/python/zope/app/intid/__init__.py", 
line 110, in register
   key = IKeyReference(ob)
 File 
"/home/jmo/philikon-local-components/lib/python/zope/interface/interface.py", 
line 691, in __call__
   raise TypeError("Could not adapt", obj, self)
TypeError: ('Could not adapt', Theme('A theme'), <InterfaceClass 
zope.app.keyreference.interfaces.IKeyReference>)
