Asked two other users to ssh remotely to my server and noted that the GLib error can also appear on a normal session close (exit the shell) . This is more evidence that the Glib-CRITICAL error is a symptom rather than the cause of the ssh-hang bug. It is also evidence that both successful and buggy-hang session-closes are all resulting in the GLib-CRITICAL error.
In the (no hang) cases, I see only two GLib-CRITICAL errors, as opposed to 3.
