[Dear Aurélien, please reply to me and to the bug address, otherwise I can only see your replies on the mailing list web archives, which is unpractical, and your replies fail to show up on the bug log!

The following part looks problematic: | The Lines KSplash theme is © 2013 Martin Klapetek, © 2014 Aurélien Couderc | under the GPLv2 with artwork from Juliette Taka Belin, Nuno Pinheiro under the | GPLv2 license. First of all, the artwork by Juliette is not under the GPL v2 or any later version, not under the GPL v2 (only). But the question is: are the other artwork also under the GPL v2 or any later version? It's not too clear from the description, but, *in case* the Lines KSplash theme is derived from the artwork by Juliette which is based on the Debian “Open Use” Logo (with the “Debian” label), we could again face the issue due to LGPLv3 / GPLv2 incompatibility... Please check with the relevant copyright holders and update the debian/copyright file accordingly. There may be issues with the following parts, as well: | The Joy GDM is © 2012 Paul Tagliamonte GPLv2, with work | from all the previous authors of that file, and artwork from Adrien Aubourg under | the GPLv3 license. | | The Joy KDM theme is © 2012 Eshat Cakar and © 2010 Roman Shtylman GPLv2 | with artwork from Adrien Aubourg under the GPLv3 license. | | The Joy KSplash theme is © 2012 Eshat Cakar, Nuno Pinheiro, Riccardo Iaconelli GPLv2 | with artwork from Adrien Aubourg under the GPLv3 license. | | The Joy grub theme is © 2012 Paul Tagliamonte GPLv2, using artwork from Adrien | Aubourg licensed under GPLv3 license. Any of these four themes may be troublesome, if is a work derived from GPLv3 artwork and from GPLv2 parts is created. Since the Joy artwork by Adrien Aubourg was previously licensed under the GPLv2 and has subsequently been re-licensed under the GPLv3 (without modifying the artwork itself, if I understand correctly: please confirm!), then we may solve the issues with these four themes by stating that: "The Joy theme is © 2012 Adrien Aubourg and released under the GPL license, version 2 or 3." Another issue could be: | Spacefun plymouth theme is © 2010 Aurelien Couderc and released under the GPLv3 | license, using artwork from Valessio S. Brito. I am not sure: is the part of the Spacefun plymouth theme that's copyrighted by you a script that loads Valessio's artwork? Or is something that combines with Valessio's artwork, thus creating a whole work derived from both parts? In the former case I can see no problems; in the latter case, there's again an incompatibility issue (GPLv2 vs. GPLv3). -- http://www.inventati.org/frx/ fsck is a four letter word... .....................................................
