Bug Description
I have about 30 photos and 30 videos on the phone.
When starting the gallery app, I scroll the carousel all the way to the right, to force all thumbnails to be loaded. (That's while there are still lots of spinners shown.) All the videos appear at the right-hand end of the carousel. Most of them have good thumbnails but, randomly, a few of them show a black thumbnail.
Looking in the cache, we do not report any failures or other errors. When looking at the cache with thumbnailer-admin, I see that we have cached a completely black image in the full-size cache. The only way for that to happen is if vs-thumb gives us a black thumbnail without reporting an error.
Looks like streamer is to blame. (I'm seeing this with two concurrent vs-thumbs running.)

This also happens with a max-extractions set to 1.
I'm also occasionally seeing the default music thumbnail that Victor reported. But, on scrolling the carousel, that one goes away and is replaced by the correct thumbnail (or a black one, where we have cached a black one).
dbus log shows nothing but successes for the thumbnailer.
