Thanks! Now I found the right construction.

gtk.stock_add((('gtk-about', '_Credits', gtk.gdk.MOD1_MASK, 
gtk.gdk.keyval_from_name('C'), 'gtk20'),))

The main problem was the comma after the first ). And that I only use
two () instead of three.

As I want to create a stock item for the button Credits in a gnome about
window, I wounder why there is not stock item gtk-credits or gtk-about
or anything else.
