Thanks for the patch.

Could you please provide a way to reproduce the issue that you're
seeing?  We don't have anyone onboard that is deeply familiar with this
code, I think, and it is security-sensitive.  Therefore, I'd like to be
careful when making changes here.

If we could have unit tests for this, it would be even better, of course.
