Calculator gives wrong answers after undo

[F.H.]

On a clean installation of Ubuntu 14.04, 64-bit. Steps to reproduce:

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 me the wrong answer!!!

See attached screenshot.

Apparently this has been a problem through Ubuntu 13.04 and 13.10. I also just noticed it when I went from 12.04 to 14.04.

Any updates regarding this bug? I often do simple calculations like below and the calculator always produces wrong results:
1. 11 x 120 = 1,320 (correct)
2. 1,320 x 11,500 = 15,180,000 (correct)
3. Press undo
4. 1,320 x 11,300 = 171.534.000.000 (wrong)
