"ObjectManager" has 2 references to its children: one in "_objects"
and one as a direct attribute. You deleted the direct attribute
but forget to delete the reference in "_objects", thus making
the "ObjectManager" data structure inconsistent.

The easiest way to fix this is something like:

    from OFS.DTMLMethod import DTMLMethod
    object_manager.Documents_catalog = DTMLMethod()
    object_manager._delObject('Documents_catalog')

Then commit.


This is also the easiest way to get rid of broken objects (as
it avoids the inconsistencies in the first place).
