It should not be happening, but it is possible to truncate an image outside of qemu while qemu is running (or any of the qemu tools using the block layer. raw_co_get_block_status() should not break then. While touching this test, replace the existing "truncate" invocation by "$QEMU_IMG convert -f raw".
