There are only two places in the code that could print this. The one
in read_index_from() can't happen unless is_null_oid() is broken (very
very unlikely).
The other one is in write_locked_index() which could happen in theory
but I don't understand how it got there. If you could build git, could
you try this patch and see if it helps?
