minitar.rb gives undefined method `size' for nil:NilClass (NoMethodError)

I was running the following script.

require 'rubygems'
require 'archive/tar/minitar'
file = "Amazon.com- Mind Performance Hacks- Tips & Tools for Overclocking Your Brain (Hacks)- Books- Ron
Hale-Evans.webloc"

out = Archive::Tar::Minitar::Output.new("compress.tar")
  Archive::Tar::Minitar::pack_file(file, out)
out.close

I get the errors as seen below:

/opt/local/lib/ruby/gems/1.8/gems/archive-tar-minitar-0.5.2/lib/archive/tar/minitar.rb:432:in `split_name': undefined

    from compress.rb:34

Something seems to be wrong with the filename of my file.
The script I used and the file to be compressed are under the same directory.
archive-tar-minitar (0.5.2)
ruby 1.8.7 (2008-08-11 patchlevel 72) [i686-darwin9]

I am facing the same issue on archive-tar-minitar (0.5.2). I am using ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin10.8.0]

I've got a fix for the problem. Will create a pull request soon. Just needs a " unless ret.nil?" since @io.read can return nil on EOF.

Note that this will still error out, but it will now correctly raise Archive::Tar::Minitar::FileNameTooLong. The filename is 114 characters long in the example provided; in default tar behaviour, files can only be 100 characters long.
