I started my Zope with bin/instance debug and tried:
>>> from Products.CMFCore.utils import getToolByName
>>> root = app.plone
>>> types_tool = getToolByName(root, 'portal_types')
>>> type_name = 'MyTypeOne'
>>> type_info = portal_types.getTypeInfo(type_name)
>>> type_info
<DynamicViewTypeInformation at /plone/portal_types/MyTypeOne>
>>> tmp_folder = root.temp
>>> new_content_item = type_info._constructInstance(tmp_folder, 'shiny_new_object')
Traceback (most recent call last):

ValueError: Product factory for MyTypeOne was invalid
So, my product factory is invalid. But in which way; how should it look like?
In my profile/default/, I have a factorytool.xml:
<?xml version="1.0"?>
<object name="portal_factory" meta_type="Plone Factory Tool">
<factorytypes>
<type portal_type="MyTypeOne"/>
<type portal_type="MyTypeTwo"/>
</factorytypes>
</object>
types.xml:
<?xml version="1.0"?>
<object name="portal_types"
meta_type="Plone Types Tool">
<object name="MyTypeOne"
meta_type="Factory-based Type Information with dynamic views"/>
<object name="MyTypeTwo"
meta_type="Factory-based Type Information with dynamic views"/>
</object>
One of them type definitions, types/MyTypeOne.xml:
<?xml version="1.0"?>
<object name="MyTypeOne"
meta_type="Factory-based Type Information with dynamic views"
xmlns:i18n="http://xml.zope.org/namespaces/i18n">
<property name="title">MyTypeOne</property>
<property name="description">

<property name="content_icon">SomeExisting.png</property>

This should be pretty default; I'm still in the beginning, and of course like to be able to see my content objects before continuing to implement futher behaviour.
Base __init__.py, largely like created by paster create -t archetype example.archetype (taken from this old reference manual which, alas! contains some now-broken links):
"""Init and utils."""
from zope.i18nmessageid import MessageFactory
from Products.CMFCore import DirectoryView
from Products.CMFCore import utils as cmfutils
DirectoryView.registerDirectory('skins', globals())
from MyCompany.MyPackage import config

from Products.CMFCore import utils
archetypeMessageFactory = MessageFactory(config.PROJECTNAME)
def initialize(context):
"""Initializer called when used as a Zope 2 product.

content_types, constructors, ftis = atapi.process_types(
atapi.listTypes(config.PROJECTNAME),
config.PROJECTNAME)
for atype, constructor in zip(content_types, constructors):
utils.ContentInit('%s: %s' % (config.PROJECTNAME, atype.portal_type),
content_types=(atype, ),
permission=config.ADD_CONTENT_PERMISSIONS[atype.portal_type],
extra_constructors=(constructor,),

What can I do to find and/or fix the problem?
Any additional information needed?
Thank you!
