This is why I always recommend $Data::Dumper::Useqq in such situations. Putting quotes some kind of delimiters around the variables you want to debug is of course a good thing, but if you're dealing with *lines* and have a problem, just use 
use Data::Dumper;
$Data::Dumper::Useqq = 1; # shows all non-printable characters
print Dumper \@lines;

(I also prefer to dump a reference, this avoids the big mess of many $VAR314159...)
edit: I even have a useful mapping for vim on my homenode which lets you debug with only very few keystrokes. (for emacs it looks a bit more complicated)
