Thanks for reporting this. QED is not widely used and its features have been incorporated into qcow2, QEMU's native image format. Since there is no development effort behind QED it is unlikely that this bug will be addressed. Patches are always welcome though!

But `qemu-img check` says that one of them has 1 leaked cluster. I wrote my own tool and it does not find any error. Both files attached, as well as debug output from my program. Both files are about 4G in size after unpacking. Unpack with `tar -S` to handle sparse files. And also, I know, that QED is deprecated, but anyway, seems qemu-img has bug.
