I tried running a pack on the database via fsrecover.fs and here's
what I get:

-----

You need to provide the full traceback so we can tell where it is coming
from.

My guess (though I'm surprised by the particular error) is that you have
perhaps got content owned by users in a user folder outside the site
that is no longer accessible when you mount the database on its own. If
that is the case then you need to write a script to fix up the
__ac_local_roles__ on the affected objects.
