	* gtk/gtkcellrendererpixbuf.c (gtk_cell_renderer_pixbuf_set_property):
	removed redundant calls to g_object_notify().
	(gtk_cell_renderer_pixbuf_get_size): removed redundant casts, see
	bug #108236.

	* gtk/gtktextiter.c (_gtk_text_iter_get_segment_char)
	(_gtk_text_iter_get_segment_byte): return 0, not NULL (these
	functions return an integer value).
