title: GTK+ segmentation fault
body: <p>utter total 100% coding noob here. I am experimenting in GTK+ and C and I'm trying to create a basic window which has an image over it.</p>
  
  <p>This is my (probably cringeworthy) code:</p>
  
  <pre><code>#include &lt;gtk/gtk.h&gt;
  
  
  int main( int argc, char *argv[])
  {
    GtkWidget *window;
    GtkWidget *fixed;
    GtkWidget *button;
    GtkImage *image;
  
    gtk_init(&amp;argc, &amp;argv);
  
    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_window_set_title(GTK_WINDOW(window), "GtkButton");
    gtk_window_set_default_size(GTK_WINDOW(window), 640, 480);
    gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
  
    fixed = gtk_fixed_new();
    gtk_container_add(GTK_CONTAINER(window), fixed);
  
    image = gtk_image_new();
    gtk_image_set_from_file(GTK_IMAGE(image),"/home/testbed/Downloads/efnbxw.jpg");
  
    gtk_fixed_put(GTK_FIXED(fixed), button, 50, 50);
    gtk_widget_set_size_request(button, 80, 35);
  
    g_signal_connect(G_OBJECT(button), "clicked",
        G_CALLBACK(gtk_main_quit), G_OBJECT(window));
  
    g_signal_connect_swapped(G_OBJECT(window), "destroy",
        G_CALLBACK(gtk_main_quit), NULL);
  
    gtk_widget_show_all(window);
  
    gtk_main();
  
    return 0;
  }
  </code></pre>
  
  <p>What did I do wrong?</p>
  
  <p><strong>Scrap the above code, it's just entirely incorrect</strong></p>
  
  <pre><code>#include &lt;gtk/gtk.h&gt;
  
  int main( int argc, char *argv[])
  {
      GtkWidget *window, *image;
  
      gtk_init(&amp;argc, &amp;argv);
  
      window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
  
      gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
      gtk_window_set_default_size(GTK_WINDOW(window), 230, 150);
      gtk_window_set_title(GTK_WINDOW(window), "Image");
      gtk_window_set_resizable(GTK_WINDOW(window), FALSE);
  
      gtk_container_set_border_width(GTK_CONTAINER(window), 2);
  
      image = gtk_image_new_from_file("/home/testbed/Downloads/efnbxw.jpg");
      gtk_container_add(GTK_CONTAINER(window), image);
  
      g_signal_connect(G_OBJECT(window), "destroy", G_CALLBACK(gtk_main_quit), NULL);
      gtk_widget_show_all(window);
      gtk_main();
  
      return 0;
  }
  </code></pre>
  
  <p>^^Heres my new code. It compiles and displayed a window with my selected image.</p>
  
  <p>Can anyone here help me code this so that when the image is clicked, the application closes?</p>
