Sorry to sound negative, but I don't think either of these issues has been resolved yet. The one you were hitting is a different bug than this one (it's a bzr-hg bug, not a bzr bug). No relevant changes have been made in bzr-hg trunk since you originally hit it so I suspect it's a bug that is related to incremental imports not working. You're very likely to hit it again when your upstream branch changes.
