I did a mistake, I saw his message in the debian-legal and I asked him 
directly.

Yes, now I have read the thread and I begin to see the complexity. My attempts 
to contact with upstream where null. Only vague answers. In our private 
mails, Aurelien and I understand that it's not free software because 
the "preamble". Howeber, that part it's not the license, so? :-)
But this is too thin for my taste ... I don't to put debian in problems. To me 
the best solution is to have a clear answer from Upstream, but this is 
difficult.

that's another soft interesting but no free software.

Aurelien did it. I did it in the contact and I interchanged some "polite" 
mails with some people from there. But nothing clear.

Ok, but if you link with Qt of you are free soft or proprietary paying a 
licence to the Nokia people.

Ignore the license issues. If really you have a component that link with OCC 
and QT and the license is not clear, really is a good reason to denounce 
them.

Yes, it too complex and bizarre.

nops, thanks to you for the work done.
