Start a new thread and run the worker_thread()


Qt Code: 
  1. QThread *settingsFileUpdaterThread = new QThread;
  2. settings_agent.moveToThread(settingsFileUpdaterThread);
  3. settingsFileUpdaterThread->start();
  4. QMetaObject::invokeMethod(&settings_agent, "worker_thread", Qt::QueuedConnection);

Qt Code: 
  1. void SettingsFileRetrievalAgent::worker_thread()
  2. {
  3.   while(1)
  4.       status = updateSettingsIfPossible();
  5.  
  6.      if (status == RETURN_SUCCESS_CACHE_UPDATED)
  7.      {
  8.          emit updatedSettingsNotification(); //segfault
  9.      }
  10.      for( int count = 0; count < 2; ++count )
  11.        sleep( 1 );
  12.   }
  13. }

I have other threads that are just about identical and they don't seem to have a problem when emitting a signal.
