non-plugin c/libgimp program execution problem

[Ben Gross <bgross@xxxxxxxxxx>]

I'm trying to write a standalone c program that can scale jpeg images.
I decided to try and leverage the gimp api via libgimp.  I can
successfully compile and link the following simple program:

#include <gimp.h>
#include <gimpfileops_pdb.h>
#include "libgimp-include.c"

int main(int argc, char** argv)
{
    gint32 img, drawable;
    gboolean status;

    /* load jpeg */
    img = gimp_file_load(GIMP_RUN_NONINTERACTIVE, "myjpeg.jpg",
"myjpeg.jpg");

    / * get drawable - needed to save */
    drawable = gimp_image_active_drawable(img);

    /* scale the image */
    status = gimp_image_scale(img, 50, 50);

    / * save the image */
    status = gimp_file_save(GIMP_RUN_NONINTERACTIVE, img, drawable,
"myjpeg2", "myjpeg2");

    exit(0);

}

Note: libgimp-include.c contains the following:

GimpPlugInInfo PLUG_IN_INFO =
{
    NULL,
    NULL,
    NULL,
    NULL
};

When I execute this program, the following assertion is made:

Glib-CRITICAL :     file ghash.c: line 138 (g_hash_table_lookup):
assertion 'hash_table != NULL' failed

LibGimp-ERROR : could not find handler for message: 5
aborting...

Is it possible to use libgimp without creating a plugin ?  Any idea how
to get this code to run ?

Thanks for your time and attention to this matter.
