[Zope-dev] _getProductRegistryData('zclasses') returns non-existent Products -- permission to muck around?

[John Ziniti]

My ProductRegistry has references to products
which no longer exist in my Zope installation.

This causes a variety of problems in lots of
different places when other products try to get
more information about all the products in the
ProductRegistry (obviously).

1) How does this occur?

2) Is it OK to put my boots on, get in there
    and manually delete entries which refer to
    non-existent Products?

TIA
