           Summary: cloud-kw.pl: can crash with divide by zero error
           Product: Koha
           Version: HEAD
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Command-line Utilities
        AssignedTo: frederic at tamil.fr
        ReportedBy: galen.charlton at liblime.com
         QAContact: koha-bugs at lists.koha.org


Around line 177 cloud-kw.pl calculates $delta which it uses in a division
around line 189:

my $delta   = $max - $min;

However, if $max and $min are the same (which can happen in a small test
database or if scanning an index of a unique identifier field), $delta is set
to 0, and cloud-kw.pl will crash at the division.
