Registry Login: Email EOF

Hi,

today i updated to gitlab 8.12.7 and since then the docker login command is not working from my ssh-runner:

gitlab-ci.yml

deploy_docker_to_dev:
  stage:
      deploy_docker_dev
  script:
    - docker login -u gitlab-ci-token -p $CI_BUILD_TOKEN registry.gitlab.intern.com
    - docker pull $CONTAINER_RELEASE_IMAGE

console output

$ docker login -u gitlab-ci-token -p $CI_BUILD_TOKEN registry.gitlab.intern.com
Email: EOF
ERROR: Build failed: Process exited with: 1. Reason was:  ()

The strange thing is that the same command is working form my dind-runner:

gitlab-ci.yml

build_docker_image:
  image: docker:latest
  services:
    - docker:dind
  before_script:
    - docker login -u gitlab-ci-token -p $CI_BUILD_TOKEN registry.gitlab.intern.com
  stage: build_docker
  script:
    - docker build -t $CONTAINER_RELEASE_IMAGE .
    - docker push $CONTAINER_RELEASE_IMAGE

console output

$ docker login -u gitlab-ci-token -p $CI_BUILD_TOKEN registry.gitlab.intern.com
Login Succeeded
$ docker build -t $CONTAINER_RELEASE_IMAGE .

Before the update the docker login command worked with both runners. I don't understand why the login command asks for an password?

Thanks Greets Kilian
