PHP fatal error in backup and restore module


I’m having some issues with the new backup and restore module (FreePBX Distro 1.812.210.57).

I made a schedule on server B to restore from server A. SSH keys are created, tested and work fine.
When I have configured the backup schedule and press “Save And Run” I get this error and nothing is restored:

Saving Backup 2…Intializing Backup 2

Restoring backup…
PHP Fatal error: Cannot use string offset as an array in /var/www/html/admin/modules/backup/ on line 603

Anyone who can help me with this issue?

Ok, tried some thing myseld, when I leave out the voicemail template the error is gone. As soon as I put it back the error is there again.
I don’t use voicemails so with that the problem (for me) is solved.
