Thanks. Unfortunately I couldn't get more info from the crash file. I also did a quick test with a windows 10 machine, but it connected just fine to the samba shares I prepared on xenial, with and without authentication, and your smb.conf changes. It used protocol 3.11. I don't have a win7 vm to test atm.
If you can reproduce the crash somewhat reliably, I would appreciate a test with the packages available in this ppa: https://launchpad.net/~ahasenack/+archive/ubuntu/samba-no-protocol- segfault-1818638 It's still building as I write this.
