Hmm.  Well, that "(null)" is the problem and indicates that a null
pointer was passed to a printf-like function internal to tla.   I.e.,
it indicates a bug.

At first glance, I see only one path through the code that could have
this result -- if arch was unable to read the name of your archive
from the archive.

The bug in arch here is that when that happens, it should panic and
remark that your archive has been bogosified.   It doesn't, at the
moment (and I've fixed that now) --- so the 0 propogates and winds up
in your checksum file.

So the next question is:  Is there an "=meta-info/name" file in your
archive and are its permissions such that you can read it?

And then the next question after that is: are you committing to this
as a local archive or over some network protocol?

The fix here, assuming that you trust your archive, will be to delete
the checksum files, then make a mirror of your archive, then turn you
mirror into the real archive and discard the horked real archive.

But we have to figure out why the archive name is getting lost before
you should try that.
