#182 Adding a two field index generates a NPE on query
I have an album class (for a picture website) with a name, year, month and day. I want to quickly fetch all the albums for a given year/month so I created an index on year/month. This queries fine without the index, but when I add the index I get a NPE:

I am attaching a test project that duplicates this error.
Extract the project and do a 'mvn test' to reproduce.
Test project showing above error.
