Two problems... You'll be lucky if the object can respond itself (ie. run the stop() method) while it is being destroyed. Try connecting to a function instead. The instance is being destroyed when the interpreter exits and after your application has terminated. To destroy it while your application is running add "del c" after the call to app.exec_().
