[DRE-maint] Bug#557023: Barby::Code128: private method split called for nil

[Wayne Conrad]

Package: libbarby-ruby1.8
Version: 0.3-1
Severity: normal
Tags: patch


Creating a new instance of Barby::Code128 with a legitimate string can
cause a stack trace.  One such string is the empty string:

      Barby::Code128.new("", 'B')

The stack trace is:

/usr/lib/ruby/1.8/barby/barcode/code_128.rb:239:in `characters': private method `split' called for nil:NilClass (NoMethodError)
	from /usr/lib/ruby/1.8/barby/barcode/code_128.rb:364:in `valid?'
	from /usr/lib/ruby/1.8/barby/barcode/code_128.rb:162:in `initialize'
	from ./foo.rb:15:in `new'
	from ./foo.rb:15

foo.rb (attached) reproduces the problem two different ways.
