I've found other bug reports on segfault of mate-screensaver. However,
those don't mention that if the screensaver crashes, then the computer
goes into auto-sleep, upon resuming from sleep the lockscreen is
bypassed. No lockscreen is presented and full access is available as the
last user logged on.
