It turns out that the image was really corrupted, in fact qemu cannot use it (it says unbootable disk).
It was qemu itself that corrupted it, but I fear this is another problem, and I can not reproduce nor diagnose it.
So I think this bug should be closed, unless someone wants to see the corrupted image.
