named crashed with SIGABRT in isc_assertion_failed()

[Art Pina]

It was probably Bug #1553460 above, but it happened during a Remmina RDP session from Ubuntu 15.10 to a 16.04.
I really don't know what caused it, but it happened the, "Authenticate is required to change your own user data" pop-up that I need to get rid, but don't know how (I recall telling xrdp or vnc to add a password layer, but now I think that was silly!)
