This may be https://bugzilla.samba.org/show_bug.cgi?id=13315, found also in https://bugzilla.samba.org/show_bug.cgi?id=13315, but we don't even have the crash file and I can't reproduce it at the moment by just connecting using SMB1: it won't crash.
** Bug watch added: Samba Bugzilla #13315 https://bugzilla.samba.org/show_bug.cgi?id=13315 -- You received this bug notification because you are a member of Ubuntu Server, which is subscribed to samba in Ubuntu. https://bugs.launchpad.net/bugs/1829916 Title: The Samba 'panic action' script, /usr/share/samba/panic-action, was called for PID 31240 (/usr/sbin/smbd).

The Samba log files may contain additional information about the problem. If the problem persists, you are encouraged to first install the samba-dbg package, which contains the debugging symbols for the Samba binaries.
