    gtester-report: cope with binaries with no test cases
    
    It's possible that a given binary may conditionally decided not to run
    any test cases (e.g. since they are all slow but -m=quick is currently
    in use) In this case the xml may contain <testbinary> nodes with no
    <testcase> children. This was resulting in a divide by zero when
    calculating the green â?? red color interpolation.
