The connect call in dcopslot.rb has 'volatile' as true, so the connect only 
works if the sender exists:

result = slottest.connectDCOPSignal("dcopsignal", "SenderWidget",
 "testEmitSignal(QString)", "mySlot(QString)", true)

It will work as a KDE::Application, but the dcop ref has the pid as part of 
its name, for instance 'konqueror-1977', rather than just 'konqueror' for a
