Hello Bryan, or anyone else affected,

Accepted libreoffice into trusty-proposed. The package will build now
and be available at
https://launchpad.net/ubuntu/+source/libreoffice/1:4.2.7-0ubuntu2 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Bug description:
  [SRU justification]


  Hang or Very slow performance after replaceall or searchall massive

  Regression in Find and Replace with LO Calc 4.2 (last worked in 4.1).
  It now takes a long time to "Find and Replace" if the to be replaced
  is to nothing.

  See comment #5/#6 of upstream for reproducer.
  See commend #8 for bibisect.

  [Test Case]

  fill A column to 0
  select A column

  Replace All 0 to " " ( null space )

  [Regression Potential]
  restricted, relevant patches are currently:
  - upstream master
  - all upstream 4.4.0 alpha/beta builds
  - upstream 4-4 branch
  - backported (by me) to upstream 4-3 branch
    => thus also included in upstream 4.3.5~rc1 released on November, 27th
    => thus will also be released by upstream 4.3.5 on ~December, 18th
  - backported to 4.3.4/utopic package (downstream, Ubuntu only)
  - backported to 4.2.7/trusty package (downstream, Ubuntu only)
  - included in all current 4.3.x and 4.2.x backports in the LibreOffice PPAs
  - included in all the 4.4~beta1 builds on the LibreOffice prereleases PPA
