Comment(by Marc Randolph <mrand@…>):
Sorry, I forgot to put a link back to the Launchpad bug. The short
version is this:
1. The cause of the crash was no tuners being defined. I don't know if
that is resolved in 0.23 or not, but there were more than one report of
this causing an actual crash (which I assume is less than ideal from a
database perspective).
2. The cause for the tuners not being defined is slightly less clear. One
person had purposely removed the tuner via setup because they removed the
hardware. But the person that opened this ticket had not gone into
mythtv-setup for a Really Long Time (tm). He mentions a different backend
crash problem, so perhaps that somehow corrupted his database?
The users backend log had the following in it:

Perhaps you should re-read the installation instructions?
