	That wasn't the error.  Some of the errors turned out to 
	be the result of my not setting "return return_object"
	in a couple of defs.  Python very nicelly returned NULL.
	Still haven't managed to track the rest down.  :-(
	
	For the curious the other obnoxious error is:
	"IndexError: string index out of range"
	
	Obnoxious, because:
	A) It is supposed to be looking at a list, not a string.
	B) The actual error is several hundred lines from where
	       the message occurs.

	The file it is reading is roughly 4 MB in size.  Each line is
	roughly 420 characters long.

	Did that, and replaced most, if not all of the similar lines.
	Didn't fix the error, since it wasn't the error, but it did 
	speed up the script by a considerable margin.  :-)
