Bugs for the GTK configuration in System Settings are not tracked at the KDE bug tracker, because the GTK configuration module is a distribution-specific add-on.
Other than that, I fail to see any error in the attached .gtkrc configuration file. If other components fail to correctly initialize because of this file, they are probably disabled by default, and need to be enabled in the .gtkrc file.
