Comment 2 for bug 1168980

While I'm not convinced that it would have been my task as a mapper to fix that or to delegate that to the origin (using a widget or not - in fact Qreator fails to follow the licenses of data it uses), I filed a bug at the gtk.Champlain widget in bugzilla, see https://bugzilla.gnome.org/show_bug.cgi?id=700569

I hope I'm right and you use the current version of that widget, as if not and they already fixed it, it would be still up to you to fix it.
