A few days ago I had posted that I figured out a way to stop Gnome Applications from looking ugly in KDE4. Turns out that my statement was not 100% accurate.
Running of gnome-settings-daemon does make the applications look normal but for some reason it only seems to do so for applications already running. If I start a new application that uses GTK then the interface still looks ugly as hell. So till I find a permanent fix, I start all the gnome applications that I need then run the gnome-settings-daemon.
I think that this could be a setting that I can change to fix the problem, but I will have to research/test the solutions before I fix the problem once and for all.
