I like new look of KDE 4.5 with icons being greyed out. However only standard icons (network, klipper, sound) are greyed out. Appliaction icons are still colorful by default.

I want to change app icons to be greyed out. So I've changed Apperance->Icons->Panel setting and marked them to be greyed out. It works only partially.

1. Some applications works fine - amarok icon is greyed out, but kmail and kopete icons are still colorful. I've found out that amarok has no svg(z) icon on my system - so maybe above setting applies only to .png icons?

2. amarok icon is greyed out and I've set it to be colorful when it's active. It doesn't work - it's greyed out all the time, it only "glows" greyed out when active.

Can you give me some hints on this? Should I make a bug report?
