Alembic stitcher fails

[Dag Atle Aas]

I have a simple sequence of a wall beeing destroyed by water. The wall is fractured in realflow. The sequence is stitched using the alembic stitcher, but when I export the stitched file something happens. When i try to open the stitched file in Blender or KeyShot, only one part of the fractured model gets a model with geometry. The rest of it does not show up. So I tried importing just one frame of the animation using the none stitched file, and then the whole model is shown.
Why is this happening and how can I fix it?
