Bob,

Can you post your exact script that you're running?

If I do the following:

class FileNotFoundException < RuntimeError
end

def load_server_list(filename)
    servers = []
    File.exist?(filename) or raise FileNotFoundException, filename
    File.open(filename).each do |line|
        next unless line =~ /^\S+$/
        next if line =~ /^#.*$/
        servers << line.chomp.sub(/\s+#.*$/, '')
    end
    servers
end

begin
    p load_server_list('serverlist.txt')
    p load_server_list('serverlist2.txt')
rescue FileNotFoundException => fnf
    puts "File '#{fnf.message}' does not exist."
    exit
end

I get exactly what I'm supposed to get in both cases. I tried this 
with both 1.6.7 and 1.7.3.
