and then ERT fails afterwards with:

@larsevj Until we know more about the failure, and how to reproduce it, we can't really get going nor triage this bug. I see that you were going to write more about it. Did you have anything more to write?

Let's add stacktrace to the exception to get more info on the error. @larsevj will write more on this.
