Getting a pixbuf from a stock icon

[Stefano Esposito <ragnacruxer gmail com>]

Hi all,

i'm trying to get a Gtk2::Gdk::Pixbuf from a stock icon. I've tried using Gtk2::Image->get_pixbuf, creating 
an image from the stock, but Gtk2 returns a critical error about the image type, which isn't Pixbuf nor 
Empty. There is any other way?Or i've miss a step?

Thanks a lot :)

Bye 
Stefano
