Looks like the error comes from repoze which means it could be 
difficult. This could be a problem with the wrong versions of repoze 
packages being installed in cz.ckan.net's virtualenv on the server, in 
which case it should get fixed when we migrate it to the new server, so 
lets wait and see if this goes away after the migration (which should be 
happening very soon)
