Was attempting to put a new splash screen (Karbon4 v 1.0) and it wouldn't install from the 'Get New Themes' window, so I downloaded the .tar.gz and selected "Install Theme File" which added it to the list and allowed me to select it but when I test it I get an 'Unable to start ksplashx' error message.

When I restart the system and actually login, the screen goes black and then loads straight to the desktop.

Is this a problem with the packaging of Karbon4 in some what that's not compatible with 4.1?

EDIT: I also experience this problem with the icons (installing new themes via "Get New Themes")

there is a bug report here on this.
