    Just out of wild curiosity, did you ever figure this thing out?  We're 
very eager to learn of bugs in Ruby so they may be fixed although it really 
looks like this was your error.  Surely, it's not outrageous to think that 
string.index(starting) can return nil.  Was this the case for you?
    Thank you...
