Thanks for adding an unknown badge for disabled builds.
It looks like unknown.png has not been committed to the repository.
This is causing the plugin to fail with the following error:
WARNING: Failed to instantiate. Skipping this component
com.google.inject.ProvisionException: Guice provision errors:
1) Error injecting constructor, java.io.FileNotFoundException: /tr/j/jh/plugins/embeddable-build-status/status/unknown.png (No such file or directory)
