It looks like the gallery app times out after a while and then displays
the "missing art" icon.

It shouldn't be doing that. On the initial load of the app with a cold
cache, we need to thumbnail loads of photos and videos. On a Mako, that
takes quite some time. We are parallelizing this as much as possible
already but, if there are many videos, the last one can take more than
30 seconds to show up.

The thumbnailer *will* eventually come up with a thumbnail, so there is
no point in timing out in the calling app.

Title:
  black video thumbnails

Status in Thumbnail generator for all kinds of files:

Status in gallery-app package in Ubuntu:

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.)
