Thank you for taking the time to report this bug and helping to make
Ubuntu better.

Please execute the following command only once, as it will automatically
gather debugging information, in a terminal:

apport-collect 1952542

When reporting bugs in the future please use apport by using 'ubuntu-
bug' and the name of the package affected. You can learn more about this
functionality at https://wiki.ubuntu.com/ReportingBugs.

ie. this bug report should have been filed with
`ubuntu-bug /var/crash/_usr_lib_systemd_systemd.0.crash`
as an uploaded file added as an attachment is less useful than the fields being 
populated from details from your machine which is done when apport tools are 
used.

Title:
  systemd randomly crashes

Status in systemd package in Ubuntu:
  Incomplete

Bug description:
  When screensaver is on, I often can't wake the system back up again.
  Screen comes, up, clock shows but frozen and login does nothing.

  I have a file `/var/crash/_usr_lib_systemd_systemd.0.crash` from
  around the incident time, so I guess it's systemd itself that's
  crashing.

  Trying to dig into the crash report, this is how far I get:
