If all else fails put some code there that generates a runtime error,
then you will get a stack trace. If you only want it to stop under
some conditions use a global variable and test it at the offending
point to find out whether to crash or not.
Fred's suggestion of using ruby-debug and putting a (possibly
conditional) breakpoint there is probably better.
