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?
