Still happens as of 2.83 Alpha, 7b8db971d4, 2020-03-02.

This causes an issue for people trying to get around the lack of support for image sequence caching. Playing an image sequence on a texture that is loaded via a scene strip works, but without prefetching frames, is still a drawback.

You'll convert many video co-pilot users if this is fixed.

~~D7514, which went into effect in 2.90 542ff416e2 & 2.83 8956e9e5f6,~~ makes it no longer crash immediately after checking Prefetch, but still crashes when I move the playhead around.

Open the file
Enable "Prefetch frames"
Go to another frame
Blender crashes

1. Open the file 2. Enable "Prefetch frames" 3. Go to another frame 4. Blender crashes

That patch is still not committed. Will commit today so you will be able to check tomorrow.
