More teststuite woes

[David Eichmann]

Hello Simon,

I had a quick look into this today, and spoke a bit with Ben about it. 
We don't have a clear answer as to what is causing this at the moment. 
We'll have to look more into this early next week.

So you've tried to validate multiple times? I.e. does the error happen 
deterministically or was it more of a one off event?
