[Alistair Buxton <a.j.buxton@xxxxxxxxx>]

This error is happening because libmlt is claiming that the video file
is -1 frames long. That is, self.p.get_length() in the thumbnailer is
returning 0x7fffffff for this file. Suggest perhaps an
assert(self.p.get_length() < 0x7fffffff) in the thumbnailer, this causes
openshot to gracefully reject the file. I also made a small test script
as follows:


import mlt

p = mlt.Producer(mlt.Profile('quarter_ntsc'), 'openshot_test.mkv')
print p.get_length()


This segfaults with no output.

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.
