i18 not working correctly with custom validators

What steps will reproduce the problem?
1. creata custom validator with some messages dict by your own messages
i used 'invalid_name':_('you cannot use %(username)s as login')
2. when keeping the user lang in session  the this string is not
translated, and using lazy_ugettext gives and exception saying this is not
a string (sure lazy gives lazy object) but str(lazy_ugettext('string'))
does not work as well.

What is the expected output? What do you see instead?
localized string and i got original string.

What version of the product are you using? On what operating system?
ubuntu 32bit formalchemy 1.2

Please provide any additional information below.
