Corrupt .VBOX file prevents registering VM

Description
VirtualBox sometimes fails to restore a snapshot after a VM has been powered off (even when waiting for 10s). The error output from VBoxManage snapshot restore then says something about a lock not being released. This problem is well-known, but not what this ticket is about.
As a workaround, I have found that unregistering the VM, re-registering it, and then repeating the snapshot restoration does the trick... most of the time. Today, a VM where a snapshot restore failed was successfully unregistered but failed to be re-registered because the VBOX file was corrupted.
Here's what the HardDisks-tag of the corrupt VBOX file looked like:

The corruption in the VBOX file is as follows:
- Many snapshot hard disks were missing as evidenced by the fact that the number of Snapshot-tags is much larger than the number of HardDisk-tags.
- The inner-most hard disk caused re-registering to fail with the error message: "Medium ... cannot be closed because it is still attached to 1 virtual machines"
- There is no reference to the inner-most snapshot hard disk in the remaining VBOX file, although the corresponding VMDK file is present in the Snapshots folder.
I was able to repair the HardDisks-Tag of the VBOX file to a working state by grep-ing all the Image-tags and nesting HardDisk-tags in order of appearance of the Image-tags.
Here's what the HardDisks-tag of the working VBOX file looks like:
