Fix bug 5797 (Critical received when double-clicking on throbber):

	* src/nautilus-window-private.h:
	* src/nautilus-window.c: (location_change_at_idle_callback):
	Callback to do actual location change at idle time instead of
	right inside the property bag callback from the throbber.
	(throbber_location_change_request_callback): Use the new idle
	approach instead of changing the location right away.
	(nautilus_window_destroy): Cancel the idle if it's still
	outstanding.

	* libnautilus-extensions/nautilus-file.c:
	(nautilus_file_get_string_attribute_with_default): Mark a string
	for translation.
	(get_description): Mark some warning strings for translation since
	they are warnings we think real users might see.

	* applets/launcher/.cvsignore:
	* applets/preferences-applet/.cvsignore:
	Ignore some files.
