Very interesting, glad you found issue

I can not reproduce your issue, if database server is not available (mysql down or no network available), Kodi comes up without connection to database and library is empty. That's it. Never seen that Kodi does not come up.
Maybe difference to your environment is, don't have any entries in audio db, onliy in video db.

But will keep it in mind
