Docker Hub - Automated Build failed, but local build without problems

Question

I have created the repository ldaume/docker-highcharts-server in the Docker Hub Registry which is connected to a github repository which contains the Dockerfile.

If I build the image locally it works like a charm.

But the automated build fails with the error Unknown Build Error. and no logs. The only content I can see in the build informations is the Dockerfile, so docker had no problems with github ;).

Any ideas?

In my scenario I had a file in my current directory that was not checked in, but in my Dockerfile I had it COPYing it into the container. Have you looked into that possibility?
