I was able to fix my problem by performing a rollback. Instructions here:

deployment-or-pending-transaction-to-google-app-engine-in-easy-steps-simple-tuto

Not sure why nothing was being outputted to the log, though.
Also, instead of Python 3.3, try installing Python 2.7. I think GAE won't work 
with any versions above this.
