Specifying an inaccessible location in nc-backup.cfg causes backups.php to crash and admin panel to be inaccessible

[Halloran]

If there is an inaccessible or non-existent location specified as the 'DESTDIR -> value' in nc-backup.cfg, then backups.php will crash when you try to load the admin console at port 4443, and the admin console becomes inaccessible.

Note that you can easily end up with an inaccessible location in the nc-backup.cfg file if you, for example, attached a drive for purpose of backup, and mounted it at a temporary location for the duration of the backup. Then after the backup completes you remove le drive and the mount point goes away.

Note that this seems related to issue #1729
