In fact the clue to this was in the verbose output:

hivex: /sysroot/Windows/System32/config/SOFTWARE: trailing garbage at end of file (at 0x245b000, after 8557 pages)

This error means that when scanning the SOFTWARE registry file in this
guest, we came across a page which was not marked with the 'hbin'
header.

As far as we know, this means the registry is really corrupt (or
something odd has happened, such as it's been zero-padded).

Since there's no official documentation for registries, we don't
actually know if it is valid for completely empty pages to exist.
