[Zope] Problem with adding items to ZClass instance

I looked at it, and found it fishy. The strange thing is, I tried to
reproduce it, but I can't. To be sure I added a tiny table plus to an
instance not a straight tiny table and a ZODBC adapter, but I doubt whether
this would make a difference. Anyway, they both work straight away. This is
getting very strange indeed. It seems strange things are happening to your
namespace.

I can think of some things that may cause problems, but this is all
speculation.

This may be a bug, but then it's a special one. Anything special about your
ZClass - what does it derive from (just objectmanager? anything else that
might cause strange behaviour?).
Is there a subobjects tab in it's definition? Are the products in there?
