Comment:
Well, I'm just reporting my findings.

My first suspects would have been either lightdm, lightdm-gtk3-greeter or light-locker. But none of them had any recent updates. I first tried downgrading xfce4-session, but that didn't change anything, so I checked which other package that was updated around the time the bug appeared. So I tried xfce4ui, which I never noticed existed before.

It might be that one of the light* packages is incompatible with the new xfce4ui package and thus the error occurs, and nothing is really wrong with xfce4ui. But for me and for now, it doesn't matter which package ultimately is the culprit, downgrading xfce4ui made the error disappear from my system.

I mentioned the settings, because default is to have a drop-down list of all existing users. With the default settings one would probably not notice anything different - because one never has to type in any user name and all user names are always "visible".

The how and the why is for devs to figure out that know / understand how these different packages interact with one another.
