ESB running in servers view gets NPE after fabric:create

I am working my way through the IDE tutorial, and was on this section: http://fusesource.com/docs/ide/2.1/tutorials/RiderTutDeployProfile.html

I started the esb in the server view, but after I did fabric:create in the shell view, I got the stack trace below in the console. After this it becomes impossible to use the esb, even if you stop and delete the server definition and re-add it. It continually prompts for a password, but won't accept it and prints "Error connecting 0.0.0.0:8101 : SSH Authentication cancelled." in the shell view
