problem with svg file license

[Jaromír Mikeš]

Hi,

while updating zam-plugins I am getting lintian error:

E: zam-plugins source: license-problem-cc-by-nc-sa
dpf/dgl/src/oui-blendish/resources/blender_icons.svg

there is also LICENSE-blender_icons.svg.txt file included in same
directory which contain GPL-2+ license

Any thoughts on this issue?

best regards

mira
