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)

... 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.

try something like:

try
blah
catch( Exception => e)
puts e.backtrace
end
