Comment 2 for bug 474599

This is a bug in the ultimate-edition-themes package not gnome-colors. If Ultimate Edition is going to add their own repository over the Ubuntu or Debian repositories, they should take care to not make packages that conflict with official Debian/Ubuntu packages. Please open a bug against the ultimate-edition-themes package where ever Ultimate Edition tracks their bugs.

They should probably just depend on gnome-human-icon-theme instead of supplying their own version. If they make there own local changes they should either have ultimate-edition-themes declare a Conflicts/Replaces on gnome-human-icon-theme or install it to a different location.

Thanks pointing this out!
