This bug was fixed in the package byobu - 5.20-0ubuntu1

---------------
byobu (5.20-0ubuntu1) quantal; urgency=low

  [ Dustin Kirkland ]
  * usr/bin/byobu-status: LP: #998812
    - fix upgrades to the new width handling, where some things
      were undefined
  * usr/lib/byobu/updates_available: LP: #976928, #1010505, #999151
    - use flock when running apt-check or apt-get
      + ideally we'd use run-one here, but not yet in main or other distros
    - depend on util-linux, which provides flock
    - drop run-one usage, use flock directly instead
  * debian/control, usr/share/byobu/windows/common:
    - fix some lintian warnings and errors
  * usr/lib/byobu/raid: LP: #1006971
    - ensure raid status cache gets cleared out when done rebuilding
  * debian/postrm: LP: #996873
    - at package removal, ensure that we remove the auto-launch symlink
      if it exists
  * usr/bin/byobu, usr/lib/byobu/include/constants, usr/lib/byobu/logo,
    usr/share/man/man1/byobu.1: LP: #938920, #995412
    - fix "infinite scrolling" of status line, when using multibyte
      utf-8 characters in status
    - detect character map, and only enable utf-8 when possible
  * usr/bin/byobu, usr/bin/byobu-launch, usr/bin/byobu-status,
    usr/lib/byobu/disk_io, usr/lib/byobu/distro,
    usr/lib/byobu/include/common, usr/lib/byobu/include/constants,
    usr/lib/byobu/release, usr/lib/byobu/updates_available: LP: #996285
    - create new BYOBU_TEST global, which is one of:
      [command -v, type, which]
    - command -v doesn't exist in busybox, type does
  * usr/lib/byobu/ec2_cost, usr/lib/byobu/include/shutil,
    usr/lib/byobu/rcs_cost: LP: #1013220
    - gracefully silence status notifications that require /proc/net/route
      when it's not really there (cygwin, mac)
  * usr/share/byobu/profiles/tmux: LP: #1012348
    - fix status activity/alert bolding
    - seems upstream tmux changed the option name from "alert" to "activity"
  * usr/share/man/man1/byobu.1: LP: #977225
    - add documentation about the status line background colors
  * usr/lib/byobu/include/constants: LP: #954031
    - use the sed --follow-symlinks option to keep from recreating files,
      especially .profile and .bashrc

  [ Dustin Kirkland and Daniel Lee ]
  * usr/lib/byobu/disk_io, usr/lib/byobu/mail, usr/lib/byobu/network:
    - LP: #962730, #998202
    - clear out cache on a few other status notifications where we go
      from activity, to none

  [ https://launchpad.net/~ktyubuntu ]
  * usr/lib/byobu/logo: LP: #1004712
    - fix Red Hat logo detection
  * usr/lib/byobu/logo: LP: #1004722
    - add apple distro and logo

@kirkland - Definitely interested in progress on this issue in Precise - it impacts all of our AWS instances.

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
