Have you considered switching to map?

As for debugging, I'd try tracking it down using p

lines = file.readlines("\x15").map do |line|
	line.chomp!("\x15")
	line.sub!(/^\n/, "")
	line = "<someTag>" + line + "</someTag>"     if line =~ /^\*{3}/
	p [:line, line] # comment me out after debugging
	line
end

p [:lines, lines] # comment me out after debugging

puts lines
