I guess you talk about the > derived work (the KDM theme)? Possibly: I was talking about whatever combined artwork built from CC-by-v3.0 and GPLv2 material. The quoted sentences gave me the impression that such artwork was created.

No, I am not. CC-by-v3.0 is GPL-incompatible, as it includes restrictions not present in the GPL. The same holds for previous versions of CC-by and for CC-by-v4.0 as well, unfortunately. > > > > I think that Juliette Belin should be asked to re-license the Lines > > theme under the terms of the GNU GPL v2. > > Or, at least, to dual-license it. > > Maybe you forgot to add her to the mail recipients, then? [...] It seems that she reads the debian-desktop mailing list: she has replied, showing kind willingness to re-license. I would be more definitely happier, if she decided to re-license her artwork under the terms of the "GNU GPL v2 or later", or, at least, to dual-license it under "GPLv2+ or CC-by-v3.0", in order to maximize the opportunities to create derivative works from the various themes. Please note that all the other themes included in the desktop-base package are GPL-licensed and can thus be combined with each other in order to create derived themes. The Lines theme is the only GPL-incompatible theme included in the package... This reason to re-license (or dual-license) holds even if we conclude that the license incompatibility is not troublesome for the Lines theme as *currently* included in the desktop-base package. -- http://www.inventati.org/frx/ fsck is a four letter word... .....................................................
