if you really want to log, why not just include the private header and do the logging? 
we do it in our derived q(core)application::notify, when catching exceptions during notify:

#include <../../src/qtbase/src/corelib/kernel/qobject_p.h>

  //...
  QMetaCallEvent* metaCallEvent=dynamic_cast<QMetaCallEvent*>(event);
  if(metaCallEvent)
  {
    eventInfo+="\nmetacall event";
    eventInfo+="\nevent id: "+QString::number(metaCallEvent->id());
    eventInfo+="\nevent sender: "+getObjectInfo(metaCallEvent->sender());
    eventInfo+="\nevent: "+QString::number(metaCallEvent->signalId());      
  }
