Construct your ioslave without GUI disabled, like in the code below:

static const KCmdLineOptions options[] =
{ "+protocol", I18N_NOOP( "Protocol name" ), 0 },
{ "+pool", I18N_NOOP( "Socket name" ), 0 },
{ "+app", I18N_NOOP( "Socket name" ), 0 },

extern "C" {
int KDE_EXPORT kdemain( int argc, char **argv )
KCmdLineArgs::init(argc, argv, "kio_foobar", 0, 0, 0, 0);
KCmdLineArgs::addCmdLineOptions( options );
KApplication app( true, true ); // note: GUI enabled

KCmdLineArgs *args = KCmdLineArgs:arsedArgs();
MyProtocol slave( args->arg(0), args->arg(1), args->arg(2) );
return 0;
