Can you think of any reason why this wouldn't work?

GtkWidget *cmds_menu;
GtkAction *action;
GtkWidget *w;

cmds_menu = gtk_menu_new();
action = GTK_ACTION(gtk_builder_get_object(builder,  
"commands_menuitem"));
w = gtk_action_create_menu_item(action);
gtk_menu_item_set_submenu(GTK_MENU_ITEM(w), cmds_menu);

/* Applications from cfg file
*/
for (i = 0; i < g_list_length(app_cfg->procs); i++) {
    struct app_proc *proc = g_list_nth_data(app_cfg->procs, i);
    assert(proc != NULL);

    action = gtk_action_new(proc->name, proc->desc, NULL, NULL);
    w = gtk_action_create_menu_item(action);
    gtk_menu_shell_insert(GTK_MENU_SHELL(cmds_menu), w, -1);
    gtk_widget_show(w);
}

Do you have a link for that?  I'd really appreciate it.

The problem is that I am set to release tomorrow.  I have to finish  
this tonight, and I noticed other issues (namely with toolbars) going  
from 3.4.5 (debian/unstable) to 3.5.2 (debian/experimental).  And I'm  
already quite tired :)
