Is there some way I can force python to throw an exception now, so my debugger can catch it and let me know where in my code the originating call is?

You need to set the warning filter to "error", which you can do either with 
warnings.simplefilter at the start of your program or by setting the 
PYTHONWARNINGS environment variable.
