Unfortunately, the bug occurred again a few minutes ago. This means that uninstalling light-locker and using xscreensaver instead is not enough to prevent the bug from occurring.
AFAIK, doing so avoids light-locker creating possibly short-lived X servers (for the purpose of asking password for unlocking screen while allowing to open a new session). Thus I believe that the bug is not triggered by running several X servers. Still, I've noticed that the bug is not active for the whole machine at a time, but can be active on an X server (for example, while typing password to unlock) and inactive on another (main session) or vice versa. All in all, this and bug https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/1558236 make (for our usage pattern at least) two important regressions that 16.04 introduces.
