Title:
  soffice.bin crashed with SIGSEGV in
  EditView::GetFieldUnderMousePointer()

Status in libreoffice package in Ubuntu:
  Confirmed
Status in libreoffice source package in Trusty:
  Fix Released

Bug description:
  [Impact]

   * over 3.000 crashes  (thus possible data loss) in the last month on errors.ubuntu.com
   * likely a regression-update from the 4.2.7 security update -- no earlier crashes reported on errors.ubuntu.com

  [Test Case]

   * no good repro instructions known

  [Regression Potential]

   * low, we have had most of the 4.2.7 -> 4.2.8 patches already vendor patched on our version
   * 4.2.8 is in https://launchpad.net/~libreoffice/+archive/ubuntu/libreoffice-4-2 since 2014-12-05 with no problems observed

  [Other Info]

  While working in a spreadsheet, Libreoffice froze and this error
  turned up.
