Title:
  Dragging video to timeline eats RAM

Status in “openshot” package in Ubuntu:
  Confirmed

Bug description:
  I made a little demo video which is 15M .mkv containing h264/FLAC
  encoded.

  Import into openshot and then drag to the timeline. Computer freezes
  up as OpenShot eats all available memory and swap and eventually gets
  killed by the kernel OOM killer.
