My point is that I don't know what T should be if I don't know what that 
method returns. And since it doesn't exist in the standard D-Bus 
implementation, I can't check my local copy for that return type.

You mentioned it's a dictionary. So T is probably QMap<Key, T> or 
QHash<Key, T> (both work fine). You need to register the type with QtDBus, 
which means you must declare it as a metatype first.

typedef QHash<Foo, Bar> FooBarHash;
Q_DECLARE_METATYPE(FooBarHash)

And in code:
    qDBusRegisterMetaType<QHash<Foo, Bar> >();

The exact types of Foo and Bar you get from the D-Bus type that your new 
function is returning.
