PyGObject is auto-converting your Python int into a GValue, but isn't
choosing the type that the C side expects. What i think should be done
in this case (other than moving tp-glib from dbus-glib to gdbus) is to
give PyGObject a hint of what type should the GValue map to, something
like:

        "keepalive-interval": GValue(60, GValue.UInt32),

Unfortunately, I don't think that exists, but would be worth asking to
the PyGObject community and checking if a ticket already exists in
bugzilla.gnome.org.
