Did you try the QtLogListener thing?

It goes something like this, where I'd recommend a breakpoint on the 
QtFatalMsg case:

void OrzApplication::onQTLog(QtMsgType type, const char *msg)
{
     namespace ba = boost::algorithm;

     LogEventPtr event(new LogEvent());

     switch (type) {
     case QtDebugMsg: event->m_level = LOG_DEBUG; break;
     case QtWarningMsg: event->m_level = LOG_WARN; break;
     case QtCriticalMsg: event->m_level = LOG_ERROR; break;
     case QtFatalMsg: event->m_level  = LOG_FATAL; break;
     default: event->m_level  = LOG_INFO; break;
     }

     if (ba::starts_with(msg, "QMetaObject::connectSlotsByName")) {
         event->m_level = LOG_ERROR;
     } else if (ba::starts_with(msg, "Object::connect")) {
         event->m_level = LOG_ERROR;
     }

     event->m_location = "Qt";
     event->m_msg = msg;

     LogSystem::the().getRootLogger().log(event);

     // or just:
     std::cerr << msg << st::endl;
}

void main()
{
     qInstallMsgHandler(&OrzApplication::onQTLog);
     QApplication a;
     osgInit():
     ...
}

Cheers,
/Marcus
