Ping @larryhastings : Please help to review the backport to 3.5 of a security fix. Thanks! |

@larryhastings the build status isn't clear. I would need help fixing it(if a fix is needed). |

There's some sort of ongoing communication problem between Travis CI and Github. It doesn't happen frequently, so if you just re-run the Travis CI check it'll usually work fine the second time. By merging a different PR, that caused this PR to be out-of-date, and updating it meant I could run Travis CI again, and now everything is fine. |

@larryhastings: Please replace |
