Public bug reported: When the screen is locked, typing anything on the keyboard doesn't lead to the password prompt. Instead, the desktop / open applications are shown for a few seconds, but the session is not unlocked, the gnome- shell crashes and the lock screen is back on. After that, the kernel log says:
