Error on alpha 35

Hi:

I did a new install today on my test and I am getting this in my log over and over:

TypeError: Cannot call method 'slice' of undefined

When I force back to alpha 27, which was what I had before, the problem goes away.

Thanks for your contributing your issue.

We have recently been actively updating the Derby and Racer packages, and both repos are now in Typescript and published with types on npm. As we have quite a few old issues open we have made the decision to close out of date issues.

If this issue still matters to you we encourage reproducing against the current versions of the repo and opening a new issue.
