Recompiling the greeter schemas as mentioned in #89[1] worked for me (Ubuntu 16.04 x64) -- haven't seen the failure in weeks, was seeing it every day or so before. I have no idea why it works, but so far so good. Wish I had time to dig deeper.
$ sudo glib-compile-schemas /usr/share/glib-2.0/schemas
