Bug description:

  The update fixes these issues:

      * Fix previous answer on undo --> (Bug #1209326)
      * Fix segfault on repeated undo
      * Update translation

  I've backported the package from utopic to trusty without any changes
  to my PPA

  I've attached a diff file. Please test and SRU to trusty.

  [Impact]

  This bug gives wrong results when undo is used.

  [Test Case]

  1. Open calculator and type "5000/60" followed by <Enter>. The
  calculator produces the right answer, 83.333...

  2. Type "/60" followed by <Enter> to divide by 60 again. The
  calculator again produces the right answer, 1.388...

  3. Press <ctrl>-Z to undo the last calculation.

  4. Press <backspace> twice to delete the last "60".

  5. Type "12" followed by <Enter>, to divide by 12 instead.

  The calculator gives the wrong answer.

  [Regression Potential]

  The fixes themselves could introduce new bugs.

  -----------------------------------------------------------------------------

  I found this bug trying to redo a calculation. Do a calculation maybe
  with decimals like I did and then press CTRL+Z and hit enter and you
  should see the bug.

  It's making a bad calculation after these steps.
