 One possible case is

svg% ls -ld aa
d---------    2 ts       ts           4096 Aug 23 13:54 aa/
svg% 

svg% ruby -e 'p FileTest.exist?("aa"); File.open("aa")'
true
-e:1:in `initialize': Permission denied - aa (Errno::EACCES)
        from -e:1:in `open'
        from -e:1
svg%

 The problem is that you don't make the right test, normally it's

K> 298	if field[5] != ""

        if field[5].to_s != ""

K> 299		if FileTest.exist?("./boiler_install_notes/#{field[5]}" )

  because this is what do ruby when you write "#{field[5]}" (i.e. it call
  #to_s for field[5])
