Trying to upload a file to my dropbox account I receive a Errno::ENOENT: No such file or directory

ruby-1.9.2-p0 > require 'dropbox'
 => true 
ruby-1.9.2-p0 > s = Dropbox::Session.deserialize( File.read( "dropbox_session_authorized.serialized" ) )
 => #<Dropbox::Session xxxxxx (authorized)> 
ruby-1.9.2-p0 > s.mode = :dropbox
 => :dropbox 
ruby-1.9.2-p0 > s.upload( '/tmp/file1.txt', '/file.txt' )
Errno::ENOENT: No such file or directory - file1.txt
