extract_stack() without any arguments is getting this from the
*current frame* which as you noted doesn't have the last exception
info included which has been popped; variable sys.last_traceback has the frames
at the time of the exception, I think.
So in your code try changing:
aRawStack = traceback.extract_stack()
to
aRawStack = traceback.extract_stack(sys.last_traceback)
