gdk_pixbuf_render_to_drawable seg fault

[Abiel Reinhart <reinhart pacinfo com>]

When attempting to use the gdk_pixbuf_render_to_drawable call to draw an
image into a drawing area, I receive a segmentation fault.

gcc version 2.96 20000731 (Red Hat Linux 7.0)

Here is the code I am using:

#include <stdio.h>
#include <gtk/gtk.h>
#include <gdk-pixbuf/gdk-pixbuf.h>

int main(int argc, char *argv[]) {

  GtkWidget *window;
  GtkWidget *drawable;
  GdkPixbuf *image;
  int width, height;
  int rowstride, bits;

  gtk_init(&argc, &argv);

  window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
  gtk_widget_set_usize(GTK_WIDGET(window), 400, 400);
  gtk_widget_realize(window);

  drawable = gtk_drawing_area_new();
  gtk_drawing_area_size(GTK_DRAWING_AREA(drawable), 320, 240);
  gtk_widget_show(drawable);
  gtk_container_add(GTK_CONTAINER(window), drawable);

  gtk_signal_connect(GTK_OBJECT(window), "destroy",
    GTK_SIGNAL_FUNC(gtk_main_quit), NULL);

  image = gdk_pixbuf_new_from_file("stdimg.xpm");
  if (image == NULL)
    perror("Image file not opened");

  width = gdk_pixbuf_get_width(image);
  height = gdk_pixbuf_get_height(image);
  rowstride = gdk_pixbuf_get_rowstride(image);
  bits = gdk_pixbuf_get_bits_per_sample(image);

  printf("W: %d, H: %d, R: %d, BPS: %d\n", width, height, rowstride,
bits);

  gdk_pixbuf_render_to_drawable(image,
    drawable->window,
    drawable->style->fg_gc[GTK_STATE_NORMAL],
    0, 0,
    0, 0,
    width, height,
    GDK_RGB_DITHER_NONE, 0, 0);

  gtk_widget_show(window);

  gtk_main();

  return 0;

}

The debugger produces the following output:

(gdb) run
Starting program: /home/abiel/test/player/pixbuf
W: 320, H: 240, R: 1280, BPS: 8

Program received signal SIGSEGV, Segmentation fault.
