Good catch, but...

... do we really need a KButtonGroup there? Is a QGroupBox (the native Qt 4 
one, not Q3GroupBox) not good enough? KButtonGroup adds button group 
functionality for radiobuttons, there are no radiobuttons here.

You also left a "class Q3GroupBox;" sitting around in filespage.h, is that 
still needed or did you forget to remove it?
