kde and gtk look and feel

[Luca Ferrari]

Hi,
I've tried to disable the "apply my kde style to gtk applications" in the kde 
settings, but when I launch a gtk application I can still see the kde style 
applied (I've restarted kde). This is annoying, since some applications 
cannot emulate well the kde style, and thus fonts and look and feel are not 
good. If I launch the application from the command line, the style is the 
original gtk one. How can I achieve this for all the gtk applications?

Thanks,
Luca
