[Bug 1509903] [NEW] After sleeping or hibernating via the K Menu options, the computer suddenly powers on again by itself, some seconds later, in Kubuntu 15.10

Public bug reported:

I recently upgraded from Kubuntu 15.04 to Kubuntu 15.10 and I've noticed
this failure: when going through the graphical K Menu > Logout > Sleep
or K Menu > Logout > Hibernate, the computer seems to do the
corresponding operation fine, but some seconds later the computer powers
on by itself, undoing the previous order to sleep or hibernate. A sample
of the corresponding log messages stored in the file /var/log/syslog is
this:

As a workaround, I'm using the command "sudo pm-hibernate" in a terminal
to hibernate the computer and this works fine, but I would prefer to use
the graphical options.

Thanks for reviewing this situation and possibly solving it.

Title:
  After sleeping or hibernating via the K Menu options, the computer
  suddenly powers on again by itself, some seconds later, in Kubuntu
  15.10

Status in systemd package in Ubuntu:
  New

Bug description:
  I recently upgraded from Kubuntu 15.04 to Kubuntu 15.10 and I've
  noticed this failure: when going through the graphical K Menu > Logout
  > Sleep or K Menu > Logout > Hibernate, the computer seems to do the
  corresponding operation fine, but some seconds later the computer
  powers on by itself, undoing the previous order to sleep or hibernate.
  A sample of the corresponding log messages stored in the file
  /var/log/syslog is this:

  As a workaround, I'm using the command "sudo pm-hibernate" in a
  terminal to hibernate the computer and this works fine, but I would
  prefer to use the graphical options.

  Thanks for reviewing this situation and possibly solving it.
