[Koha] Sudoc icons have incompatible licensing?

Hi all, I was looking at the About page as part of another patch, and noticed this bit: The Sudoc Icon Set * Les icones Sudoc * The Sudoc Icon Set is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 3.0 License by Agence Bibliographique de l'Enseignement Supérieur As I understand it, Non-Commercial is a dangerous license for us as a project, and I have concerns about including this icon set when it is so licensed. Thoughts? Feelings? Liz Rea
