There's no API for that.

It's very likely to be the cause.

You can use the libdbus-1 API by getting the pointer returned by 
QDBusConnection::internalPointer() (internal API, might change at any time) 
and cast it to DBusConnection*.

There's no equivalent in QDBusServer. If you need to do that, you'll need to 
hack the QtDBus source code.
