Signals received twice

[Erick Pérez Castellanos <erick red gmail com>]

Hi:

I think this is a bug, but I'm asking first to check,
I'm using GtkFileChooserButton and connecting to "selection-changed" signal 
and the issue is that when i changed the selected fodler in the widget, I'm 
getting the signal 4 or 5 times repeatedly.
And I think that should happens just one, Am I right ?
