I think this bug was introduced in last 3-4 weeks. It was working fine before. This bug is not consistently reproducible. I have seen this 3 times in last 10 runs. A variation of the same bug was also seen by Abhishek Singh in Eventing CI. We had discussed about this couple of weeks back. I think its worth looking into this.
