Hi!

This doesn't sound like an add-file problem but an include-problem. More 
specifically, it seems that you include gimp.h before the GObject header 
is pulled in. Did you read the GIMP include policy in 
devel-docs/includes.txt? You can see how other files in the app/widgets 
dir include gimp.h, for example gimpcolordialog.c. That file, like most 
files in that dir, includes the GObject header indirectly by pulling in 
the GTK+ header:

  #include <gtk/gtk.h>

and then after widgets-types.h comes gimp.h:

  #include "core/gimp.h"

Let us know if you need further assistance.
