Won't play music inside unity8 snap because of unknown application ID

In the unity8 snap I've been working on, I tried to play music from unity8-dash. And it doesn't do anything. Media Hub gives an error about "Invalid profile name". Seemingly from the code in apparmor/ubuntu.cpp:

    MH_DEBUG("apparmor profile name: %s", name);
    MH_DEBUG("is_unconfined(): %s", (is_unconfined() ? "true" : "false"));
    MH_DEBUG("has_package_name(): %s", (has_package_name() ? "true" : "false"));
    if (not is_unconfined() and not is_unity() and not has_package_name())
        throw std::logic_error
        {
            "apparmor::ubuntu::Context: Invalid profile name " + str()
        };

For the unity8 snap, I see:

[DD 2016-11-16 20:54:00.782937] [ubuntu.cpp:111@Context] apparmor profile name: snap.unity8-session.unity8-session
[DD 2016-11-16 20:54:00.782992] [ubuntu.cpp:112@Context] is_unconfined(): false
[DD 2016-11-16 20:54:00.783028] [ubuntu.cpp:113@Context] has_package_name(): false
Error while executing the underlying io_service: apparmor::ubuntu::Context: Invalid profile name snap.unity8-session.unity8-session

It seems like media-hub is not prepared for this new snappy world.

(Also, and separately, media-hub doesn't have a non-android video backend? I assume that's a known issue and/or there's a bug for that already.)
