#578 NPE during backup

[voji]

The following NPE thrown, in some cases during backup. I using the latest (stable) version of areca backup: areca-7.5-linux-gtk-64.tar.gz, on Ubuntu 14.04.3 LTS.

The backup location is mounted over nfs, but i think, at this point it's irrelevant.

Please let me know if you need any other information. :)

The relevant log entries:
