(The key-writability commit as discussed with release-team

 last week)

Tue Jul 22 16:34:10 2003  George Lebl <jirka@5z.com>

	* libnautilus-private/nautilus-global-preferences.c
	  (import_old_preferences_if_needed): Don't import
	  a preference if we can't write the new value

	* libnautilus-private/nautilus-sound.c (nautilus_sound_init)
	  (nautilus_sound_kill_sound) (nautilus_sound_register_sound)
	  (nautilus_sound_can_play_sound): If we can't write the current
	  sound state key, don't allow the sound preview since we won't be
	  able to kill the preview process later, and don't set the sound
	  state key if not writable.

	* src/nautilus-shell.c (save_window_states):  If we can't
	  save the start state, don't save it then.

	* src/nautilus-window.c (side_pane_size_allocate_callback)
	  (side_pane_switch_page_callback) (nautilus_window_hide_location_bar)
	  (nautilus_window_show_location_bar)
	  (nautilus_window_hide_toolbar) (nautilus_window_show_toolbar)
	  (nautilus_window_hide_sidebar) (nautilus_window_show_sidebar)
	  (nautilus_window_hide_status_bar) (nautilus_window_show_status_bar):
	  When we can't write the preference of the start state, don't set
	  it.
