The DBus specification says that
org.freedesktop.DBus.Properties.PropertiesChanged signal was added in 0.14,
but may not be supported by particular implementations. Either because they
were not yet updated to 0.14 or because they for some reason don't want to.
See
http://dbus.freedesktop.org/doc/dbus-specification.html#standard-interfaces-properties
I can't find when that specification version was released, but believe it's
not more than a year.
So try connecting to the PropertiesChanged signal. If that does not work, try
using the methods of DBus.Proxy directly instead of relying on the laguage
support. It still may not work if your server does not emit it, though.
