This bug was fixed in the package lightdm - 1.17.0-0ubuntu1

---------------
lightdm (1.17.0-0ubuntu1) xenial; urgency=medium

  * New upstream release:
    - Disable log backups - this interferes with logrotate.
    - Support using libaudit to generate audit events.
    - Handle trailing whitespace on boolean values in configuration.
    - Update example configuration to more correctly match allowed options.
    - Fix unnecessary X server from being launched when locking seats.
    - Check the version of the X server we are running so we correctly pass
      -listen tcp when required.
    - Allow reading /proc/<PID>/net/dev from within a guest session.
      (LP: #1442609)
    - Allow guest sessions to write in /{,var/}run/screen folder.
      (LP: #1442611)
    - Update guest-session AppArmor profile to be suitable for openSUSE.
    - Fix apparmor profiles for running Chromium in guest sessions.
      (LP: #1504049, LP: #1464958)
    - Fix configure failing without Vala installed.
  * Build with multi-arch
  * debian/lightdm.logrotate:
    - Use logrotate to handle log files placed in the default system log
      directory (/var/log/lightdm).
  * debian/guest*:
    - Optimize guest account creation, use OverlayFS of AuFS if available.

Title:
  Guest session needs read access to "/proc/net/dev" and/or
  "/proc/*/net/dev" for network traffic applications

  Fix Released

Bug description:
  I'm customizing my guest sessions in Xubuntu 15.04 and discovered that
  xfce4-netload-plugin can't show current net traffic. After
  investigating netload plugin source code, I've found that a possible
  reason for this strange behaviour is that guest sessions are unable to
  read /proc/net/dev and/or /proc/<PID>/net/dev.

  Could you please review current apparmor profile for lightdm-guest-
  session so it can get read access to /proc/net/dev?
