Your remark appeared (and presumably is) valid, although I do not understand
why adding acl_user folders has no problems with that. So, I additionally
defined manage_afterAdd. However I got the same error. Any more pointers? By
the way, where are 'manage_afterAdd' and friends documented?

Module QuerySet.py:
from Query import manage_addQuery
class QuerySet(Folder):
    def __init__(self, id, title):
        self.id = id
        self.title = title

    def manage_afterAdd(self, item, container):
        manage_addQuery(self, id, title)

manage_addQuery in Query.py looks like:
def manage_addQuery(dispatcher, id, title, REQUEST=None):
    dispatcher.Destination()._setObject(id, nQ)
    if REQUEST is not None:
        dispatcher.manage_main(dispatcher, REQUEST)

Traceback (innermost last):
