ec2 spot instance fails with ResutSet object has no attribute instances

We had ec2 spot instnaces working previously.
Today we started getting the following stack trace.
We monitored ec2 instances UI in amazon and as soon as the ec2 instance being created status went from pending to active ansible returned with the error.

Removing the spot instance price fixed the problem.
Can anyone else reproduce?
