NullPointerException at com.google.inject.internal.Initializer$InjectableReference.get(Initializer.java:147)

This is likely related to issue #627 (and possibly #473).

I have just reproduced this NPE in our large and complex production 
application, running Guice 3.0. Moreover, I came across a small 
test-configuration that exhibits the same exception:

https://groups.google.com/forum/#!msg/roboguice/3LW0xMEr2hI/B2Rgk9L1_kgJ

(I've attached the test-source to this report for durability/convenience.)

I can't be certain that the circumstances are exactly the same as our 
real-world app, but we do use all of the features invoked by this sample 
together.

In our case, the exception is intermittent: it only throws about 70% of the 
time.
