Error upgrading from 0.7.1 to 0.8.0

Are you sure you are on 0.8.1? This error existed in 0.8, but I fixed it yesterday morning in 0.8.1.

I can't replicate your example on 0.8.1. Can you double check?

Thanks,

Corey

Yep, I noticed that pretty much as soon as I wrote this and then promptly closed the issue.

Thanks!
