[Koha] Patron Card Creator doesn’t work

I have a new installation of Koha 16.05 on Ubuntu 14.04. As far as I can see everything works, but the Patron Card Creator. I can print card but they don’t show no barcodes nor patron pictures. Instead the logo is printed a second time on place of the photo. Who can help? BTW, I think it’s a bug: i create a new patron and it seems as it would generate automatically a password but it does not send any e-mail to the new member. I have to generate the password by myself and then the e-mail is sending.
