Two thoughts:

1) Is this a suspect version of Python+Zope? I had a lot
   of problems of this general nature with Python 2.1.1 + Zope 2.4.3,
   and when I asked on list I was told this might be the problem.
   I haven't been using Python 2.1.3 + Zope 2.5.1 long enough to
   be sure, but it does *seem* to have made some of these problems go
   away.

2) Writing __init__.py is a wee bit picky. Have you done this
   before so that you know you're doing it right?  (Have given
   all the arguments to the context.registerClass() calls, etc?)
   Did you import the module that the object is defined in into
   __init__.py? Hmm. Does the name in __init__.py agree with
   the name in the original module? (I had some objects disappear
   without generating any traceback when I renamed one of them).
   Of course, that wouldn't seem to account for the product
   being missing.  Does everything have a docstring?  I've been
   bitten by that requirement a few times.  I notice my
   initialize function has one -- I can't remember what happens
   if it doesn't, though.
