We have default out of the box install from package repository on ubuntu
10.04 that gives us problems with links having extra ?id=None parameter.
We don't have a custom theme for now. For example, each of the links at
layout_base menu have this extra parameter and they are generated as such:

   <span py:if="h.check_access('package_create')">
     ${h.nav_link(c, _('Add a dataset'), controller='package',  
action='new')}
   </span>
   ${h.nav_link(c, _('Search'), controller='package', action='index'
   , highlight_actions = 'new index')}
   ${h.nav_link(c, _('Groups'), controller='group', action='index')}
   ${h.nav_link(c, _('About'), controller='home', action='about')}

Also links to API contain ?id=None:

   <li>
     ${h.link_to(_('API'), h.url_for(controller='api', action='get_api'))}
   </li>
   <li>${h.link_to(_('API Docs'), 'http://wiki.ckan.net/API')}</li>

as well as login and register links:

   <a href="${h.url_for(controller='user',action='login')}">Login</a>
   <a href="${h.url_for(controller='user',action='register')}">Register</a>

Mostly that extra ?id=None parameter is harmless, I think, but when
going through that search link, it uses that ?id=None as a search facet.
That will of course screw up the search.
Can this be fixed with Routes config or is the issue more complicated?

Probably, or because of newer version of postgres. Unfortunately I didn't
copy the error message. But it was due to not being able to create database
for reason or another. We had 9.x version of postgres installed when I
tried the installation. After the db part of install failed, I installed
postgres version 8.4, made user account for ckan by hand and created a db
with owner being ckan. Then I ran init db script, and it worked.

According to David, disqus is not compatible with v.1.5 default theme, so  
we will
discuss what we will do with it (dump it or try to fix it).
