it did give me trouble.
the solution was to remove 'meta_types' from my class and apparently
inherit it from ObjectManager.  the method
ObjectManager.filter_meta_types was attempting to use .has_key('...')
on my tuple of metatypes (which were strings).  i am unclear as to
where zope translates these strings to some other object.

as for the manage_options, i used a bastardized version of the Folder
class'.  it works, but i am still unclear about the details.
