Karma 0.13.3 - You need to include some adapter that implements __karma__.start method! Error when using urlRoot

[codependent]

I am using Karma's latest release (0.13.3) and found that when using urlRoot in the configuration I got this error:

   You need to include some adapter that implements __karma__.start method!

However, changing the dependency back to version 0.12.31 it works:

WARN [proxy]: proxy "http://localhost:3000" normalized to "http://localhost:3000/"
WARN [karma]: Port 8080 in use
WARN [karma]: Port 8081 in use

This can be reproduced with the code located here https://github.com/codependent/karma-demo

1. Start the server with node index.js
2. karma start test/karma.ng-scenario.conf.js

👍 just ran into this too.

downgrading to 0.12.31 worked for me as well. Also, had to downgrade grunt-karma down to 0.11 because of peerDeps.

Published as 0.13.8

Thanks @dignifiedquire for the quick turnaround.
