I had a look at the KDevelop code and now have:

	KProcess *proc = new KProcess( this );
	*proc << "konsole";
	proc->setUseShell( true );
	connect( proc, SIGNAL(processExited(KProcess *)), this, SLOT(slotProcess( 
KProcess * )) );
	proc->start( KProcess::NotifyOnExit, KProcess::CTtyOnly );

which does the trick. :)

Thanks for the pointers
