Hi all. It is correct that I'm also maintainer of this package, as you can see on http://maemo.org/packages/view/harmattan-theme/

This thread is marked as bugtracker of package.

I have no skills for making themes, so I have no intention to produce material, but just make new releases when new material is made by somebody else.

Current (0.4-1) version depends on 'harmattan-icons-pack-for-white-themes' which was in uninstallable condition until I today fixed it to the repository (that was reason for my 12 days silence about new version).
