Verification code should be a required field

I've tried this again, and I got this trace:

2011-09-16 10:29:53,561:561.000108719 - ubuntu_sso.main.windows - INFO - Emittin
g remote signal for on_email_validation_error with callback <bound method EmailV
erificationController.on_email_validation_error of <ubuntu_sso.qt.controllers.Em

Peer will receive following PB traceback:
