What did you do?

I ran rkt config with a sample configuration file I copied from the website.

What did you expect to see?

A description of my config from rkt config.

What did you see instead?

This looks like it's fixed by #3910, which isn't included in any release yet.

You're welcome to double check that fixes it, but based on that trace and the changes in the PR, it seems quite likely it will.

I just tried out 1.30.0 and rkt config now works!
