[gtkada] Problem with File_Chooser in Windows

[Michael González Harbour]

Hello:

I am using GtkAda 2.14.1. with Gnat-GPL-2010.

I have written an aplication that uses a File_Chooser widget for "Open" 
and "Save" actions. It works fine in Linux, but in Windows the widget 
ignores the "Save" button (while I get the warning message "Error 
loading theme icon 'gtk-save' for stock: Icon 'gtk-save' not present in 
Theme").

When I use the testgtkada program in Windows and invoke the 
File_Chooser_Button option to open a file, it works fine. However, when 
and I try to set the File_Chooser action to "Save" with the provided 
"Properties" button, the application refuses it, with the following 
warning:
"gtk_file_chooser_button_set_property: Choosers of type 
'GtkFileChooserButton' do not support 'GTK_FILE_CHOOSER_ACTION_SAVE'.

If I try the same in Linux, the "Open" action works fine, but the 
"Properties" button fails when I click it, with the following error message:
raised INTERFACES.C.STRINGS.DEREFERENCE_ERROR : i-cstrin.adb:191

Any idea on how to use the File_Chooser widget for "Save" action in 
Windows? (other that switching to the File_Selection widget)

Thanks,

Michael Gonzalez.
