The message is 

./emacs -Q
XSetWMSizeHints: % % width_inc: % height_inc: %
XSetWMSizeHints: % % width_inc: % height_inc: %

(emacs:833): Gtk-WARNING **: Allocating size to Emacs 0x1d503e0 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate?
XSetWMSizeHints: % % width_inc: % height_inc: %
XSetWMSizeHints: % % width_inc: % height_inc: %
XSetWMSizeHints: % % width_inc: % height_inc: %
XSetWMSizeHints: % % width_inc: % height_inc: %
XSetWMSizeHints: % % width_inc: % height_inc: %
