Remove icons from KDE task manager

Question

How do I remove these icons from KDE's task manager?

I am using KDE 4.8 on Arch Linux, I've looked everywhere but I cannot for the life of me find out how to remove them

Thanks

Found it

Open the following

~/.kde4/share/config/plasma-desktop-appletsrc

and remove

[Containments][1][Applets][5][Configuration][Launchers]
Items=preferred://browser?wmClass=%20,preferred://filemanager?wmClass=%20
browser=preferred://browser, , ,\s
filemanager=preferred://filemanager, , ,\s

Then log out and back in and the icons will be gone
