The immediate reproducer (not very useful for you) is virt-v2v, if you
enable lazy_refcounts by hacking the call to qemu-img here:

https://github.com/libguestfs/libguestfs/blob/master/v2v/v2v.ml#L102

I'll try to come up with an actual reproducer, but I stress it's still
going to use libguestfs because that's the only sane way to run qemu
for the purposes of this test.
