if you're using GTK+ 3.x, then yes: that's the correct migration.
all (new|set)_from_stock() should be replaced with (new|set)_from_icon_name().
in
general, you should also question the icons usage: overloading the
UI with visual cues ends up distracting the user, and in general the
written word is more apt to describe actions than a bare icon, unless
the icon is unequivocally tied to a specific action (e.g. standard
images).
ciao,
Emmanuele.

=========================
Thanks Emmanuele.
In my case, I'm putting the icon in a dialog with a message instructing the user on exactly what's wrong. Having said that, perhaps the icon is just redundant. I never thought about it before.
Anyway, thanks again.
