Bug 7318

This is somehow a corner case, since you probably won't encounter it unless you are switching between Toaster modes. It is a bug nonetheless, so there it goes. 

Steps to reproduce:

1. Start toaster in build (managed) mode and visit the all builds page
2. Stop toaster
3. Source the environment script
4. Start Toaster in analysis (interactive) mode 
5. If you are redirected to the no builds state, type this url in your browser

localhost:8000/toastergui/builds

The page fails to load. This is the trace:
