Hi agentzh,

Thanks for giving rr a try!  I'm sorry that you're running into this
problem, but I'm sure we'll be able to resolve it quickly :).

Do you mind filing this and future bugs in our github tracker[1]?  The work
will happen on github, so filing the issue there initially saves everyone a
step :).

Thanks!

Cheers,
Chris
