	* components/html/ntl-web-browser.c (main): properly handle
	  gconf error, and init it to NULL first.  This will avoid
	  crashes on error.

	* libnautilus-extentions/Makefile.am,
	  libnautilus-extentions/nautilus-preferences-private.h,
	  libnautilus-extentions/nautilus-preferences.c:  Add a
	  nautilus_preferences_handle_error functions for use in
	  nautilus-preferences and user level manager to handle and reset
	  GConf exceptions.  The reason a new "private" header was added is
	  to preserve the gconf encapsulation outside libnautilus-extentions,
	  plus it's only useful there.

	* libnautilus-extentions/nautilus-preferences.c

	  (nautilus_user_level_manager_set_default_value_if_needed)
	  (nautilus_user_level_manager_compare_preference_between_user_levels):
	  Handle GConf exceptions.  Try to revert to sane behaviour on
	  errors, such as using defaults.  Remove all the asserts for
	  conditions that arise from gconf errors.  Fixes bug 672
