    Fix ZeroDivisionError in reconstructor.stats_line

    Despite a check to prevent zero values in the denominator python
    integer division could result in ZeroDivisionError in the compute_eta
    helper function. Make sure we always have a non-zero value even if it
    is small.

    NotImplemented:

     * stats calculation is still not great, see lp bug #1488608
