Thanks,your patch is correct. I also added a unit test for retr_rate() to reproduce the issue.

() Attached is a patch to fix something that at least looks like it can cause a crash, but looking at this stack trace, which already shows the formatted string "7.95 GB/s" in the output string, I'm not sure if that is really the fix/cause.
