Subject: error message help

My program is hitting an error and showing me:
c:/ruby/lib/ruby/1.8/drb/drb.rb:743:in `+': can't convert nil into 
String (TypeError)
    from c:/ruby/lib/ruby/1.8/drb/drb.rb:743:in `open'

    from c:/ruby/lib/ruby/1.8/drb/drb.rb:1084:in `method_missing'
     ... 12 levels...
    from stclient.rb:30:in `run'
    from stclient.rb:30:in `initialize'
    from stclient.rb:36:in `new'
    from stclient.rb:36

How do I get ruby to show me the middle 12 levels?  The problem is 
probably in the middle there, but I don't know what method.
