Well, the 3 lines just before that one should have printed the register. Even if you have only one control declared, like a main window, you'll get something.

If you got nothing, then you must be running your code while object_register is empty = {}.

Which means you're calling your set color routine before any control whatsoever has been created, OR some routine is setting object_register = 0 or {}. Do a grep for object_register, and you'll see there's only one line where the register can be affected, and that line always appends a tuple. Even a 3-line program with one window will trigger a lookup when you set() some property:

include GtkEngine.e 
 
constant win = create(GtkWindow) 
set(win,"modify bg",0,"red") 

{ 
  {160861224,35}, 
  {162875392,184} 
}
