In Products.ZODBMountPoint.MountedObject.py around line 373:

     # Add a faux object to avoid generating manage_afterAdd() events
     # while appeasing OFS.ObjectManager._setObject(), then discreetly
     # replace the faux object with a MountedObject.
     faux = Folder()
     faux.id = mo.id
     faux.meta_type = loaded.meta_type
     container._setObject(faux.id, faux)
     # DM 2005-05-17: we want to keep our decision about automatic
     #  mount point creation
     #del mo._create_mount_points
     container._setOb(faux.id, mo)
     setMountPoint(container, faux.id, mo)

The error was raised on the _setOb() line.

Removing the whole faux dance made everything work correctly. May be 
this is not necessary any more. Should I create a ticket?
