Cannot set default directories for a client

Client: Ubuntu 12.04 LTS. Trying to set up default directories for a specific client fails.

Settings from the server:

Allow client-side changing of settings: NO
File backups | Default directories to backup: /home/user/Documents  

When starting a full backup from the server, got the following error:

Constructing of filelist of "machine" failed: no backup dirs. Please add paths to backup on the client (via tray icon) or configure default paths to backup.  

21.03.14 12:06  	ERROR  	Sending settings to client failed  

The same path settings works, if set up on the client gui.

Does the client pick up the path change if you disable the “Allow client-side changing of settings” option under settings in the web interface?
