Rails - Sep 2006 - Strange error in jcode.rb when converting range to array

In my rails app I''ve line with the following code:

("a".."z").to_a

Simple enough and it''s been working for a while. Last night this line
started throwing the following error:

undefined method `[]'' for nil:NilClass
/usr/local/lib/ruby/1.8/jcode.rb:83:in `succ!''
/usr/local/lib/ruby/1.8/jcode.rb:94

I looked up jcode.rb and the comments for this file say that it''s
"#
jcode.rb - ruby code to handle japanese (EUC/SJIS) string"

This is the part of jcode.rb that throws the error (line 83)

78  def succ!
79    reg = end_regexp
80    if self =~ reg
81      succ_table = SUCC[$KCODE[0,1].downcase]
83      begin
84	self[-1] += succ_table[self[-1]]
85	self[-2] += 1 if self[-1] == 0
86      end while self !~ reg
87      self
88    else
89      original_succ!
90    end
91  end

Debugging is difficult because if I restart the app, the problem goes
away..for a while.  Has anyone else encountered this error before?

It''s obviously being caused by something I''ve added to my app
recently. I just can''t figure out what.

ruby -v
ruby 1.8.4 (2005-12-24) [i686-darwin8.5.2]

Thanks
