Crash on android when saving contact

Hi,
first i'm not sure about version, i use the one in npm and github : 2.3.1 but it doesn't reflect version in issue tracker.
Step to reproduce :

var contact = navigator.contacts.create(

{ id: "12345", displayName: "John Doe", emails: [new ContactField('work', "john@doe.com", true)] }

);

contact.save(); crash with this stack trace :
