My bad, it's ok, I had to specify QVariantList in result and not list.

class Some(QObject):
  
   fakenotify = Signal()

   @Property('QVariantList', notify=fakenotify2)
    def withprop(self):
        with db_session:
            return self.db.Page.recents()

    @Slot(result=list)
    def withslot(self):
        with db_session:
            return self.db.Page.recents()

in some ListView using as model:
some.withprop works
but
some.whithslot() fails with : qrc:/qml/main.qml:54: TypeError: Cannot call method 'withslot' of null
