I get this error when setting the 'Volume' property:

org.qtproject.QtDBus.Error.InternalError: Internal error

It's an error that occurs inside the software that implements MPris (I 
tested with firefox playing a youtube video), not inside 'gb.dbus'.

The 'gb.dbus' component knows that the 'Volume' property is a Float ('d' 
DBus signature), and actually correctly sends a 'double' to the DBus API.

So I have no idea what the problem is at the moment.
