pam_limits: Unknown kernel rlimit 'Max realtime timeout' ignored

I've got this error more fully silenced in a later commit which should be available soon.

This bug was fixed in the package pam - 1.1.3-2ubuntu1

---------------
pam (1.1.3-2ubuntu1) oneiric; urgency=low

  * Merge with Debian to get bug fix for unknown kernel rlimits. Remaining
    changes:
    - debian/libpam-modules.postinst: Add PATH to /etc/environment if it's
      not present there or in /etc/security/pam_env.conf. (should send to
      Debian).
    - debian/libpam0g.postinst: only ask questions during update-manager when
      there are non-default services running.
    - Change Vcs-Bzr to point at the Ubuntu branch.
    - debian/patches-applied/series: Ubuntu patches are as below ...
    - debian/patches-applied/ubuntu-rlimit_nice_correction: Explicitly
      initialise RLIMIT_NICE rather than relying on the kernel limits.
    - debian/patches-applied/pam_motd-legal-notice: display the contents of
      /etc/legal once, then set a flag in the user's homedir to prevent
      showing it again.
    - debian/update-motd.5, debian/libpam-modules.manpages: add a manpage
      for update-motd, with some best practices and notes of explanation.
    - debian/patches/update-motd-manpage-ref: add a reference in pam_motd(8)
      to update-motd(5)
    - debian/libpam0g.postinst: drop kdm from the list of services to
      restart.
    - debian/libpam0g.postinst: check if gdm is actually running before
      trying to reload it.
    - debian/local/common-session{,-noninteractive}: Enable pam_umask by
      default, now that the umask setting is gone from /etc/profile.
    - debian/local/pam-auth-update: Add the new md5sums for pam_umask addition.
    - add debian/patches-applied/pam_umask_usergroups_from_login.defs.patch:
      Deprecate pam_unix' explicit "usergroups" option and instead read it
      from /etc/login.def's "USERGROUP_ENAB" option if umask is only defined
      there. This restores compatibility with the pre-PAM behaviour of login.
      (Closes: #583958)
  * Dropped changes:
    - debian/patches-applied/027_pam_limits_better_init_allow_explicit_root:
      no need to bump the hard limit for number of file descriptors any more
      since we read kernel limits directly now.

pam (1.1.3-2) unstable; urgency=low

  [ Kees Cook ]
  * debian/patches-applied/027_pam_limits_better_init_allow_explicit_root:
    - only report about unknown kernel rlimits when "debug" is set
      (Closes: 625226, LP: #794531).

  [ Steve Langasek ]
  * Build for multiarch. Closes: #463420.
  * debian/patches-applied/027_pam_limits_better_init_allow_explicit_root:
    don't reset the process niceness for root; since it's root, they can
    still renice to a lower nice level if they need to and changing the
    nice level by default is unexpected behavior. Closes: #594377.
