I suspect this may have something to do with the bzr 2.3 upgrade.

Thanks,

I went ahead and requeued this one, to see if it was transient. We used to get this sort of error in bzr when a root id changed, etc. I think some of the workaround for that required calling a new helper function. So it could just be that whatever code is applying the changes needs to be updated for this.

(Basically, I remember fixing something like this since 2.1, but I don't see why it would start failing now.)
