Model validation hasn't been fully implemented yet, and that's the only thing that should be calling Field.validate_full() at the moment. This will be fixed at that time.

The suggested fix isn't completely correct, since, for example, an empty string isn't valid there either.

For anybody reading this in the near future, the area that needs changing is Field.validate_full(), which isn't line 116 any longer.

This code was removed in [8348]. Can't really call it fixed since #6845 isn't integrated yet, but its patch doesn't appear to have this problem. At any rate the code mentioned here no longer exists so there's nothing to fix for this ticket.
