	* libnautilus-extensions/nautilus-directory-async.c:
	(nautilus_directory_is_anyone_monitoring_file_list):
	Made this function public because it's needed to get the
	assert right.
	(start_or_stop_io): Use it by the new public name.
	* libnautilus-extensions/nautilus-vfs-directory.c:
	(vfs_is_not_empty): Use the new function to get the assert
	right, which fixes bug 2706 (crash at startup with
	bookmark for nonexistent trash file).

	* libnautilus-extensions/nautilus-trash-directory.c:
	(remove_trash_volume): Fix a NautilusDirectory leak.

	* libnautilus-extensions/nautilus-glib-extensions.c:
	(print_key_string), (free_hash_tables_at_exit):
	Print keys before complaining about hash table so you
	see them first if you have things set to drop into
	the debugger on warnings.
