How did you defined the model ?

What does the function get_pixbuf returns ?

  treeview = gtk_tree_view_new ();
  gtk_widget_show (treeview);
  gtk_container_add (GTK_CONTAINER (the_container), treeview);

  text_renderer = gtk_cell_renderer_text_new();
  image_renderer = gtk_cell_renderer_pixbuf_new();

  store = gtk_tree_store_new(2, GDK_TYPE_PIXBUF, G_TYPE_STRING);  

  image_col = gtk_tree_view_column_new_with_attributes ("Image",
                                                      image_renderer,
                                                      "pixbuf", 0,
                                                       NULL);

  text_col = gtk_tree_view_column_new_with_attributes ("Text",
                                                      text_renderer,

                                                       NULL);

  gtk_tree_view_set_model (GTK_TREE_VIEW (treeview), 
                           GTK_TREE_MODEL (store));
  gtk_tree_view_insert_column ( GTK_TREE_VIEW(treeview), image_col, 0);
  gtk_tree_view_insert_column ( GTK_TREE_VIEW(treeview), text_col, 1);

  // this is yours
  gtk_tree_store_append (GTK_TREE_STORE (store), &iter,NULL);
  pb = get_pixbuf("play.xpm"); // does it returns a GdkPixbuf ?
  gtk_tree_store_set(GTK_TREE_STORE (model), &iter, 0, pb,-1);
