I suppose "fix" is a bit misleading. After coffee and further inspection
of the script, the "fix" is to extract the IP addresses from the
corrupted database file, add them to the firewall ruleset, and delete
the corrupted database.

That's not so helpful, unless sshguard can do the same -- manually
extract the IPs, delete the database file, and write them into a new
one. Detecting the corruption successfully is probably the hardest
part...
