	* preferences.c (preferences_load_from_bonobo_db):
	(preferences_load_from_bonobo_pbag): Default to TRUE on enabled;
	check value of wallpaper_filename to set wallpaper_enabled if
	wallpaper_enabled could not be found

	* background-properties-capplet.c (setup_dialog):
	(apply_settings): Check for error condition after creating
	preferences object

	(bonobo_color_to_gdk): Made argument const
	(DB_GET_VALUE): Removed
