Fine. I get that. So is there a better or correct way of doing this so 
that I get the original error that was raised.

Aaaah. so you mean if i check for my_form before freeing, then ... since 
no new exception is raised, the original exception will be displayed.
So I _should_ say:

ensure
if !my_form.nil?
   my_form.free ... etc
end
