Thanks for your bug report.
I guess this is probably related to my patch series aiming at giving nicer output in 'git range-diff', which probably introduced some bug.

I don't think there's anything you should do here, this sounds like a bug in Git that should be fixed. It would be great if you could help with some more details per above though, otherwise it's going to be hard to track this down.
