Thanks! It turns out that we weren't running debuginfo-tests. Trying to
find a mac I can ssh into to reproduce this.

Another side question: is there usually an etiquette for how long a
greendragon bot is allowed to stay broken? I don't want to leave it that
way for too long while working on my fix if it bothers others too much.

Thanks,
Leonard
