HashDistance() with hash of file 192 bytes length gives unclear error 'Apples != Grapes'

[oneumyvakin]

STEPS

1. Create file with 192 bytes length:

   123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012

2. Try to HashDistance() with some random file:

   package main
   import (
   "github.com/glaslos/ssdeep"
   "fmt"
   )
   func main() {
   deepMaingo := ssdeep.NewSSDEEP()
   deepMaingoStr := deepMaingo.Fuzzy("main.go")
   fmt.Printf("deepMaingoStr: '%s'\n", deepMaingoStr)
   deep192 := ssdeep.NewSSDEEP()
   deep192Str := deep192.Fuzzy("192.txt")
   fmt.Printf("deep192Str : '%s'\n", deep192Str )
   distance, err := ssdeep.HashDistance(deepMaingoStr, deep192Str )
   fmt.Printf("Distance: '%d' Error: '%s'\n", distance, err)
   }

ACTUAL RESULT Error 'Apples != Grapes' is unclear:

block size: 3, file size: 192, n/bs: 64
deep192Str: '3:OWGukOWGukOWGukOWGukOWGukOWGukOWGukOWGukOWGukOWGukOWGukOWGukOWGU:OWGukOWGukOWGukOWGukOWGukOWGukOw,"192.txt"'
Distance: '0' Error: 'Apples != Grapes'
