Using the real Oxygen icons?

[Evropi]

Hi,

I want to change to the standard Oxygen icons with the cool folder icons and stuff introduced in KDE SC 4.7 or whatever it was. However, it seems the system can... only use the Oxymentary icon set (which is the default)? I've switched to vanilla Oxygen from System Settings > Application Appearance > Icons, but this is what I get.

Any solution to this problem? I'm using Mint 14, which is updated to KDE 4.9.4 so I should be getting a more consistent selection of icons, surely.
