Subject: [PATCH] Ticket 50063 - Crash after attempting to restore a single
 backend

Description:  While we do not support backup/restore of individual backends,
              it should not crash the server either.  PR_OpenDir will crash
              if the file name is NULL, so this fix just prevents the crash
              by returning an error if the filename is NULL.
