I'm not entirely positive what happened yet, but I believe the following is what happened.

1. Started up 1.6.0, loaded some data
2. Stopped 1.6.0
3. Started up 1.6.1-SNAPSHOT over the same instance to test some new code I was writing
4. Stopped 1.6.1-SNAPSHOT
5. Re-started 1.6.0 to run a demo
6. Above error

My guess is that this is from the thrift 0.9.0 to 0.9.1 change for 1.6.1, which means that 1.6.1 cannot presently downgrade back to 1.6.0. I need to do some more testing to be sure, though.
