i was seeing TypeError: 'NoneType' object is not iterable errors without stack traces, which inspired this issue...but that actually came from the WSGI handler, outside of my code, when i didn't return anything (ie returned None) from my application() function. exceptions raised from inside my code do log stack traces. so, closing.
