Can't connect when you have :eval-in :leiningen in your project.clj

[cldwalker]

From LightTable/LightTable#1316:

In a new project, just adding :eval-in :leiningen to project.clj, I got this error:

We couldn't connect.

Looks like there was an issue trying to connect to the project. Here's what we got:
