Scheduled mail "configuration and content" backup failing

[sweetrobot]

I have enabled email content and configuration scheduled backups, adn each time, the backup process results in the following error:

Line 456 error: Element 'sites': This element is not expected. Expected is one of ( properties, limits-and-permissions ).

The backups carry some weight in terms of filesize, buttdue to the error, the 'Comment' on the backups reads "This file is not a valid backup file."

Any ideas on how I could resolve this?

Best

As far as I know it was fixed in Plesk 11.0.9 MU#6
