You need to pass a KDE::AboutData instance to KDE::CmdLineArgs.init:

ruby -r korundum -e 'KDE::CmdLineArgs.init(ARGV, KDE::AboutData.new("myapp", 
"My App", "0.1")); KDE::Application.new'

I tried it in C++ and that seg faulted too with a zero KAboutData arg, so 
there isn't much the bindings can do about that..
