Couldn't find the exact number but there's a couple of upstream related issues, anyways this should be send upstream and let them decide what to do, as Sebastien said if you don't have enough space for saving files on tmp that is going to lead to multiple issues, like sessions not working, not being able to login, etc, indeed it could be better and display a message about it, feel free to send it upstream at bugzilla.gnome.org. thanks.
