You aren't telling us if the directory exists or not. Perl only gives you a helpfull warning, just in case you are trying to stat a file/directory with a newline in it - which would be a common programming error.

If you want to avoid the warning, just use

{ no warnings 'newline';
  next if -d "$dir/$current_filename";
};
