I'm afraid I can't reproduce this error. That the 
exception is raised in a module that is not supposed to be 
imported worries me. The templates directory of the 
library shouldn't be looked at after a correct init, which 
leads me to believe that the instance wasn't initialised 
properly. Could you please detail the exact steps and 
inputs used: from installing roundup to requesting the web 
page. For example, the following worked fine for me:

% python setup.py install
% roundup-admin init                            
Enter instance home: /tmp/test
Templates: extended, classic
Select template [classic]: 
Back ends: anydbm, bsddb, bsddb3
Select backend [anydbm]: 
Admin Password: 
       Confirm: 
% roundup-server -p9080 test=/tmp/test    
Roundup server started on ('', 9080)

I then request the web page http://localhost:9080/test/
