Crash when loading an alembic sequence and move the timeline.

Exact steps for others to reproduce the error
Load this .abc-sequence: 2frame_Alembic_Sequence
The frames are 1023 and 1024.
Crash message:

Btw. the geometry inside the abc archive has vertexColors, UVs and velocity. Vertex colors are working inside Blender already, but you can use these files for testing if you are going to implement UVs and motion blur.
