  QDBusAbstractInterface::call ( QDBus::CallMode mode, const QString &method,
..) doesn't return Qt::DBusMessage.
just return nil.

  iface = Qt::DBusInterface.new(SERVICE_NAME, "", "",
Qt::DBusConnection.sessionBus)
  msg = iface.call(Qt::DBus::BlockWithGui, "somemethod", param)
  p msg   # => nil
  reply = Qt::DBusReply.new(msg)  # => Error!
/usr/lib/ruby/site_ruby/1.8/Qt/qtruby4.rb:2572:in `initialize': unresolved
constructor call Qt::DBusError (ArgumentError)

This snippet of code slightly changed from examples/qdbus/pingpon/ping.rb 
 provoke error.

attach a patch to remedy this problem.
