lost Theme manager in kde 4.1
After I installed kde 4.1 (RC) the theme manager disappeared from the appearance - system settings window. I waited until the release of 4.1 but the problem is still here. Did I miss some packages? I tried both sudo apt-get update && sudo apt-get dist-upgrade
and sudo apt-get update && sudo apt-get install kubuntu-kde4-desktop
Does anyone have any suggestions? please help.
