Problems with sample publications

Hi everyone.

I am having problems with a few of the sample publications that come
with Lenya.  In particular, the ethz-mat doesn't allow me to log in to
the editor's view, it always gives me a tomcat error, specifically that
it can't find "lenya//do-login".

Looking at the page source of the login screen, I see that the action of
the login form is set to "/lenya//do-login", and by looking at the other
examples that do work, I think it should be "/lenya/ethz-mat/do-login". 
Is this correct?  How can I fix it?  I think this publication is the one
most similar to the one I need to set up. :)

Thanks a lot.
