Seth: Your requested output is perf-20171026.txt It's not clear to me what's out of the ordinary in the stack traces, except of course that once we're in the Python code of 'apport', things have unquestionably already gone to Hell. Maybe someone who's familiar with the code will have a better idea.

On a hunch, I decided to test whether the problem is related to 'seccomp' and changed /etc/ssh/sshd_config from the default # UsePrivilegeSeparation sandbox to the former standard value UsePrivilegeSeparation yes and logins started to work again. Obviously, I'd like to have the additional protection that sandboxing would give me.
