Does this fix address the problem that I have?

OpenERP REQUIRES that there is a DEFAULT product category.  I do NOT
want a default product category, I want the field to remain empty (and
blue, because it is required) to force my users to select their product
category.

This is the only place that we have found where a default is required
(the default is hard-coded to be the ALL PRODUCTS category), and this
behavior is not consistent with the rest of OpenERP.

The fix requires a re-write of the following function.  The code
containing 'cat0' should not exist at all - it sets the default category
to be (the reference to) cat0 if no default exists - it should return
nothing if no default exists.

 _default_category(self, cr, uid, context=None):
        if context is None:
            context = {}
        if 'categ_id' in context and context['categ_id']:
            return context['categ_id']
        md = self.pool.get('ir.model.data')
        res = False
        try:
            res = md.get_object_reference(cr, uid, 'product', 'cat0')[1]
        except ValueError:
            res = False
        return res
