On the buildbot server, I see the following code in lib/python/buildbot/status/mail.py:

        # GB: NEW: add test logfile excerpts
        if "test" in t: # only if the test went wrong
            for log in build.getLogs():
                if "test" in log.getStep().getName():
                    text += "\n"
                    text += "Excerpt from the test logfile:"
                    text += interpret_test_logfile(log.getText().splitlines())
                    text += "\n"
                    break

But I'm unable to find this code in the upstream code:

https://github.com/buildbot/buildbot/blob/v0.8.12/master/buildbot/status/mail.py#L742

Do we have downstream changes on buildbot? I'm asking because it seems like emails cannot be send because of these lines. Extract of logs:

Note: It seems like 0.8.14 is deployed, but I don't see any v0.8.14 tag on GitHub, the last one of the 0.8 branch is v0.8.12. https://pypi.python.org/pypi/buildbot/0.8.14 wasn't tagged in Git?
