Here's the code I ended up with after some fiddling and looking at the
GIMP sources:

static void
main_file_for_stock( GtkIconFactory *icon_factory,
        const char *stock, const char *file )
{
        GtkIconSource *icon_source;
        GtkIconSet *icon_set;
        char buf[FILENAME_MAX];
        char buf2[FILENAME_MAX];

        im_snprintf( buf2, FILENAME_MAX,
                "$VIPSHOME/share/$PACKAGE/data/%s", file );
        expand_variables( buf2, buf );
        nativize_path( buf );
        icon_source = gtk_icon_source_new();
        gtk_icon_source_set_filename( icon_source, buf );
        icon_set = gtk_icon_set_new();
        gtk_icon_set_add_source( icon_set, icon_source );
        gtk_icon_source_free( icon_source );
        gtk_icon_factory_add( icon_factory, stock, icon_set );
        gtk_icon_set_unref( icon_set );
}

then in startup:

        static const GtkStockItem stock_item[] = {
/* Can be (eg.)
 *
 *   { GTK_STOCK_COPY, N_("_Copy"), GDK_CONTROL_MASK, 'c', GETTEXT_PACKAGE },
 *
 */
                { STOCK_PAINTBRUSH, N_( "Pen" ),
                        0, 0, GETTEXT_PACKAGE },
                { STOCK_LINE, N_( "Line" ),
                        0, 0, GETTEXT_PACKAGE },
                etc.
        };

        gtk_stock_add_static( stock_item, IM_NUMBER( stock_item ) );

        main_icon_factory = gtk_icon_factory_new();

        main_file_for_stock( main_icon_factory,
                STOCK_PAINTBRUSH, "stock-tool-ink-22.png" );
        main_file_for_stock( main_icon_factory,
                STOCK_LINE, "stock-tool-path-22.png" );
        etc.

        gtk_icon_factory_add_default( main_icon_factory );
        g_object_unref( main_icon_factory );

Then you can use STOCK_LINE like any other stock item (if I've not
forgotten anything).
