OK, after debugging I found that there are two separate issues. First, one needs the gnome-icon-theme, 
gnome-icon-theme-symbolic, and gnome-themes-standard packages to actually get the icons. Second, one needs 
gtk+-3.10.3 or later, because earlier versions didn’t default to checking the “gnome” icons by default even 
though a number of gtk internal things use them.

As for the changes to your code, you can still use the stock items, you’ll just get deprecation warnings. The 
new regime is to use the icon name that the stock macro defined as, e.g. instead of GTK_STOCK_ABOUT use 
“gtk-about” or “gtk-about-symbolic”. 

I’ve pushed the necessary changes to the modulesets, including upgrading gtkmm3 and glibmm to 3.10.1 and 
2.38.1 respectively, matching the versions of gtk+-3.0 and glib.
