Can't save contact with badly formatted birthdate, no error.

[Frode Lindeijer]

When editing a contact at one.ubuntu.com/contacts trying to save the changes won't do anything if the contact's birth date is entered in the wrong format. There is no error message stating this is the problem, nor does it say on the page what format it expects.

(I'm not sure if Infrastructure, or even Launchpad is the right place to report this)
