[Interest] Question about using QtDBus

[Rogers Nate]

I have that static method in ServiceErrorLogData.cpp...

void ServiceErrorLogData::registerMetaType()
{
    qRegisterMetaType<ServiceErrorLogData>("ServiceErrorLogData");

    qDBusRegisterMetaType<ServiceErrorLogData>();
    qDBusRegisterMetaType<QList<ServiceErrorLogData> >();
}

I was calling this from my main.cpp.  Is that not a good way to do it or
did I not use it correctly?
