Thanks Bob for your answer. Using show() and hide() fix the problem when 
I use the 'Cancel' button or select a file, but not for the delete event:

I can't 'connect_simple' on 'delete' for the FileChooser, Php reports 
that this signal is unknown.

However I can connect_simple() to the 'destroy' signal and my called 
method calls hide() and then returns 'true'. In that case I have the 
same problem I had with set_visible() but in a slightly different way: 
when I call show() again, the file chooser window will appear and then 
disappear very fast, showing only the title bar for this window.
