Abend in gdk_pixbuf_new_from_file

[Bryan Brown <bbrown saltmine radix net>]

Hello,

My application (built using gtk 2.x under Redhat 9) sets up a file
selection dialog, waits for the user to select a file, then tries to read
the specified file into a pixbuf.

It's abending with a segmentation fault when it calls
gdk_pixbuf_new_from_file, the user having selected a standard
png-formatted picture file.

Here's a snippet of the relevant code:

GtkWidget *file_selector;
gchar     *filename;

[snip]

void
on_read_ok_button_clicked (GtkButton *button,
                           gpointer  user_data)
{
   gchar filename_local[BUFLEN] = "\0";
   GError *error;
   GdkPixbuf *pixbuf = NULL;

[snip]

   filename = (gchar *) gtk_file_selection_get_filename (
               GTK_FILE_SELECTION (file_selector));

[snip length checking]

   strcpy (filename_local, filename);
   gtk_widget_destroy (file_selector);

   pixbuf = gdk_pixbuf_new_from_file (filename_local,
                                      &error);

   file_selector = gtk_file_selection_new ("Select an input file");

   g_signal_connect (
      GTK_OBJECT (GTK_FILE_SELECTION (file_selector)->ok_button),
      "clicked",
      G_CALLBACK (on_read_ok_button_clicked),
      NULL);
   g_signal_connect_swapped (
      GTK_OBJECT (GTK_FILE_SELECTION (file_selector)->ok_button),
      "clicked",
      G_CALLBACK (gtk_widget_destroy),
     (gpointer) file_selector);
   g_signal_connect_swapped (
      GTK_OBJECT (GTK_FILE_SELECTION (file_selector)->cancel_button),
      "clicked",
      G_CALLBACK (gtk_widget_destroy),
      (gpointer) file_selector);
   gtk_widget_show (file_selector);
}
