[Zope] Adding a Factory results in a new ZCatalog index type

my "new" product is EXACTLY the simple "HELLO"-example out of the 
Zope-Book. No additional features or something like that.

and the result is (go to an ZCatalog => click on the Indexes-TAB => open 
"Select type to add"-menu):

FieldIndex
Hello                   <= that should not be there i think!!!!
KeyWordIndex
PathIndex
TextIndex

as I've mentioned before: same results on fresh installations of 2.4.3 or 
2.5.b4!!!

that's why i am worried about and think it must be a bug or something with 
wrong permissions or so. maybe someone could test this on his own 
installation and report the results???

I've looked at "filtered_meta_types" in the ObjectManager-Code. The "Select 
type to add"-menu in the Index-Tab of the ZCatalog will be generated out of 
this list. My "Hello"-product is in this list if i look in the menu "Select 
type to add" at the INDEX-Tab of a ZCatalog. If i am guessing right, 
"filtered_meta_types" should only contain the "meta_types" which the user 
has permissions for. and that's why i am nerving. maybe there's a security 
problem in the "standard-creation" of a new product through the web...

thank you for your help so much. hope to have made things a little bit 
clearer...
