Is the misbehaving array element really a string, and what exactly  
are you doing in your code.  In your earlier post you said:

but inspect turns things into strings.  for example I can imagine  
code like this:

ratdog:~ mike$ irb
irb(main):001:0> class Foo
irb(main):002:1> def initialize(s) ; @s = s ; end
irb(main):003:1> def inspect ; @s ; end
irb(main):004:1> end
=> nil
irb(main):005:0> array = [Foo.new("one\ntwo\n")]
=> [one
two
]
irb(main):006:0> array[0].inspect
=> "one\ntwo\n"
irb(main):007:0> array[0].split("\n")
NoMethodError: private method `split' called for one
two
:Foo
         from (irb):7
         from :0

Without more concrete information it is hard to guess at what is  
really going on!
