lightdm - Cannot unlock session if user has no password

I created an account with no password for my 3 year old child. After some time of inactivity on that account, the session locks.


Then I cannot unlock the session. Trying to unlock with an empty password does not work, and there is no password to enter.


The easy solution for now is to disable the locking of the session, but I want the computer to auto-suspend after time-out.


Why can't I unlock without entering a password? Is it a bug or a feature? Is it even a known behavior?
