Found guest-6lDH45Lx:132: and guest-MTiNKr:x:127: groups in /etc/group.

Can anybody explain what these are and why they're lurking in my configuration?

As the names suggests, these are the group counterparts for temporary guest account that lightdm has created. They are supposed to get cleaned up and removed after the session is done with but I could see that in a power-failure (for example) these could hang around. It might also be this bug.

Assuming nobody is logged in as a guest, you can almost certainly delete these lines (and /etc/passwd counterparts) safely. There may also be temporary home directories lagging behind too.

You can also disable the "guest session" functionality if you wish.
