I had already run mythfulldatabase.  I always do that.  I have been
maintaining mythtv installations for years and wouldn't ignore a step
that, apart from anything else, you're clearly told to do by
mythtv-setup every time you run a scan.

They all have entries in channum.  Some part of the process is failing,
but with no indication of what that might be in the logs, I'm left
staring at code and database schemas.
