Dear Maintainer,

your machine-readable debian/copyright file contains a files paragraph 
with a missing License:-field:

 Files: debian/*
 Copyright: 2003, Mark Purcell <m...@debian.org>
            2012, Michael van der Kolff <mvanderko...@gmail.com>

Could you please add a correspondig license entry for your files?

Thanks!
  Thorsten
