My apprentice is playing with this, and he tried this solution, which 
worked. His fix:

"What I ended up doing was manually adding in the slug values (in the 
form of an extra parameter that specified a default) that should 
havebeen retrieved by the config_value call that was throwing the error.
Here are the changes I made to Satchmo's products/urls/__init__.py:

# catbase = r'^' + config_value('PRODUCT','CATEGORY_SLUG') + '/'
catbase = r'^' + config_value('PRODUCT','CATEGORY_SLUG', 'category') + '/'
# prodbase = r'^' + config_value('PRODUCT','PRODUCT_SLUG') + '/'
prodbase = r'^' + config_value('PRODUCT','PRODUCT_SLUG', 'product') + '/'

After those changes, test2.xxxxxxxxxx.com started working again"

I am wondering why the slug values weren't there in the first place, but 
I haven't had time to look at it just yet.
