Create a project, then clone it (I used 'integration' and named it 'camel-test1'). Create a new branch and push it, make some change to src/main/java/org/example/Application.java, commit and push it.

Go into fabric8-console's source viewer, change to the 'foobar' branch, and navigate to Application.java. Click on the History button, the page will be blank and the following error shows up in the developer console:
