I'm going to be relanding this, as this appears to be test-verify only. However I'm hoping we can work out the fix soon.

Mark, what needs to be done here?

This was a new test-verify failure that seemed to be introduced when we ported the test across. It also seemed to be pretty much a permanent failure. Therefore, I think we should try and fix it as part of the QuantumBar work, or at least understand what's going on.

I've just been running this on try and it seems to have gone away now.
