In the current version from svn when I try installing the theme I get 
the following error, with full traceback:

This refers to the information in the template 
gnomeweb-plone/wgo.buildout/src/gnome.theme/gnome/theme/skins/gnome_theme_custom_templates/main_template.pt
Line 125.   I tried installing the theme without it -  it will install 
but is a very ugly/basic theme, nothing like the screenshots.
Here is the offending gnome_slots section
       <div id="sidebar"
         metal:define-slot="column_gnome_slots"
         tal:condition="here/gnome_slots">
         <metal:portlets define-slot="portlets_gnome_slots">
         <metal:gnomeportlets 
use-macro="here/gnome_slots_column/macros/slots">
         This instruction gets the portlets (boxes) for the column 
aside the content region.
         </metal:gnomeportlets>
         </metal:portlets>
       </div>


I've had a quick look around and I notice in 
gnome.theme/gnome/theme/config.py, the gnome slots portlets are defined

GNOMESLOTS = (
   'here/portlet_gnome_sidenav/macros/portlet',
   'here/portlet_review/macros/portlet',
   'here/portlet_gnome_example/macros/portlet',
   'here/portlet_calendar/macros/portlet',
   'here/portlet_events/macros/portlet',
   'here/portlet_recent/macros/portlet',
   )

and the template for the slots is:
gnomeweb-plone/wgo.buildout/src/gnome.theme/gnome/theme/skins/gnome_theme_templates/gnome_slots_column.pt

I'll be interested to try out your patches and see if I can continue on 
getting it to look like the screenshots while you're away.
