Hmmm... This is not looking good. So, I have 53 videos in my Videos
directory. Each video is a few seconds long, around 5 MB in size each. I
wipe the cache and start the gallery app, and scroll around to push
requests to the thumbnailer. Then after a while, I see this in the log:

thumbnailer-service: [01:53:35.041] "thumbnail: /home/phablet/Pictures/com.ubuntu.camera/image20150604_035240355.jpg (256,0): 1.853746 sec (HIT)"

So, something repeatedly tries to allocate 24 GB of memory. I'm not
impressed :-(

Title:
  black video thumbnails

Status in Thumbnail generator for all kinds of files:
  New
Status in gallery-app package in Ubuntu:
  New

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.)
