Lars, Bob, Hank,

The problem with the registry should have been fixed.

One little comment: this should be a fine strategy but a quick sanity
check before you accept the new dump is probably a good idea :-). It's
not only the registry that could fail, you could for example also end
up in a sitation where the ftp download doesn't complete sucessfully.

I recommend a sanity check that does the following: check whether the
file starts with a proper header, whether it ends with '# EOF' and
whether the size of the 'diff' between the current file and the old
file is acceptable (to you).

I want to apologize for the time it took to fix the problem. We do
have an escalation procedure but it clearly didn't work fast enough.
I'll see what I can do about that.
