Interceptor crashes deployed site (on Heroku)

[ceg1236]

Our site uses the Interceptor to start and stop ngLoading, since we only wanted to display the load on a particular request.
Minifying Injector somehow destroys the functionality.

The deployment finishes, but when the ngLoading is started, this error occurs:
Error: [$injector:unpr] Unknown provider: aProvider <- a

Everything worked fine running locally (before minifying).

Hope this helps, I can update with more details as they come.
