screensaver crashed on wake up

[Martin Vysny]

Sometimes when the laptop wakes up from hibernation (by opening a lid), I can immediately see my apps running and I can interact with them, without any need to input the login password. I perceive this is a serious security issue which needs to be addressed.

Perhaps the gnome-shell crashed (or the screensaver crashed), but it shouldn't simply restart without querying for the password.

I have the crash report on my machine, however apport uploaded it automatically without allowing me to add additional info. Please let me know how I can track it down.
