Using "u1sdtool --waiting-metadata" command an error is displayed

Binary package hint: ubuntuone-client

When I use the command <u1sdtool --waiting-metadata> in a terminal I receive the following error message:

###############################################################
nicola@nicola-laptop:~$ u1sdtool --waiting-metadata

Oops, an error ocurred:

All other commands, like <u1sdtool --status>, <u1sdtool --waiting-content>, etc., are working properly.
