This must be one of SVN revisions 5003 to 5008 in upstream qemu. Can you
narrow it down to one of these? I certainly don't feel like reviewing
all of them once again.

Do I understand correctly that your image fails with the kvm-73 version
of block-qcow2.c and afterwards boots with kvm-72? So the image is not
really corrupted but it's more likely an IO error which brings the OS down?
