Jaako,

To help, I've summarised the change we made to the Routes config here:
http://trac.ckan.org/ticket/1651

I can't reproduce your behaviour on our clean Ubuntu 10.04 install or
by playing around with the Routes version or Routes config.

Do check your Routes version is 1.11 though:

$ pip freeze | grep Routes

You could try changing map.explicit=False to see if that helps
(although there will likely be other URLs messed up). Otherwise, I
suggest you'll have to debug why Routes is acting differently, due to
our different environments.
