Qt Plugin Path

I use the Qt Configuration tool under K | System | Configuration to delete /usr/lib/qt3/plugins from the plugin path. I do this because /usr/lib/qt3.0.3/plugins is already there in the path and the former is just a simlink to the later. Even if I save the configuration, when I restart KDE, the later get automatically added back. HOw do I permanently get rid of it? Salman
