#274 Reinstall of products fails if not using $INSTANCE/Products

[Nate Aune]

Zope 2.7.1, Plone 2.0.3, CMFQuickInstaller 1.5.0

I have defined two additional product dirs in the
etc/zope.conf file:

products $INSTANCE/p4a-Products
products $INSTANCE/demo-Products

When I try to reinstall CMFNewsletter, CMFBoard,
PlonePayPal, or any other product which is in one of
these directories, I get the following error message.

When I move the product into the $INSTANCE/Products
directory, and restart Zope, then I can use the
QuickInstaller to reinstall the product.

The QuickInstaller should be able to detect additional
Product directories and run the Extensions/Install.py
from those dirs.

Traceback (innermost last):
