In a subscription feed with "fast loading" enabled (where feed items from YouTube are "sparse"), have some videos playing, then enqueue one or more sparse items. This only happens sometimes, and I'm not sure what causes it to happen/not happen sometimes.

Expected behavior

No crash

Actual behavior

Crash

(sorry about these short answers, what else is expected from a NullPointerException?)
