I debugged and let me to the same as Wim. g_object_notify is async.

I guess the fakesink prints are relevant to debugging, I'd propose:

1) Add a signal to fakesink 'new-message', this would be sync.
'new-last-message' is weird because new and last doesn't make sense on the same
sentence, but new-message can be confusing as there is also GstMessage on the
gstreamer context.

This allows applications to integrate this into their debugging needs in a sync
manner.

2) Add an extra property to fakesink to make it print directly to stdout to
allow gst-launch to have sync output of those messages. Or make it handle
fakesink case specially to handle the last-message signal, but then it could be
mixed with the default _notify handling and we would have even more duplicated
outputs.
