Matthew, before I start dancing around, do you think ^^ could have the same cause as 0b62af28f249b9c4036a05acfb053058dc02e2e2 which got fixed by 863a8eb3f27098b42772f668e3977ff4cae10b04?
Yes, entirely plausible. I think you have two useful points to look at before delving into a full bisect -- 863a8e and the parent of 0b62af. If either of them work, I think you have no more work to do.
