As noticed by Justin Clift <jclift@redhat.com> the licence file
was invalid so the licence (COPYING) file has been updated to
the right one and also licence changed to LGPLv2+ as discussed
some time ago - the change was done for Fedora branch however
I didn't forward-port it to the master branch yet obviously.
