You won't see this in production thanks to class caching; this only happens in dev mode, when certain modules fail to reload cleanly between requests. I created a new 0.9.1 project using just the extensions and files you posted. Switching that single config was enough to fix the error for me, so I'm not sure what to suggest... if you make any progress or get to the point where you're facing a different error, let me know and maybe I can be of more help.
