This is a GObject feature:

http://library.gnome.org/devel/gobject/stable/gobject-The-Base-Object-Type.html#GObject-notify

All GObjects emit / are supposed to emit a "notify" signal when one of
their properties changes. The property that changed will be used as the
signal 'detail', ie. the bit after '::', so in order to just catch when
the "source" property changes you would conect to the 'notify::source'
signal instead of the 'notify' signal.
