* libnautilus-extensions/nautilus-directory-async.c:
	(metafile_read_failed): First cut at only reading the metafile if the
	directory is really a directory. This might be making things worse
	for now, because I'm not sure if the file info is available at this
	point. I'll check in something better soon.

	* libnautilus-extensions/nautilus-directory.c:
	(nautilus_directory_is_search_directory): Fixed backwards test that
	would return TRUE for many non-search directories. Then I put that
	code inside #if 0 and added a version of the function that just
	checks the scheme of the URI for now. Also added FIXMEs.

	* libnautilus-extensions/nautilus-file.c:
	(nautilus_file_get_real_name): Simplfied the code a bit. Also added
	a FIXME.
