Sorry, I forgot to put a link back to the Launchpad bug. The short version is this:
- 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).
- 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:

OK. There's still a bug here in that we should check that the tuners are present before trying to run the scheduler on them, but this is mostly a configuration issue.

(the second log appears to indicate he had another instance of the backend running)

Marc,
Could we get some more context on this?
