[PS][trunk] dashboard creation

On trunk with the web client, I try to create a new dashboard, using the menu 'Settings --> Customization --> Reporting --> Dashboard creation'. I get the following error when I try to save the dashboard:

ValidateError

Error occurred while validating the field(s) arch: Invalid XML for View Architecture!

On the server terminal:

Steps to reproduce:
- Create a new dashboard
- Add one or two widgets (leads & phone calls)
- Save the dashboard
