Assuming that the backend was trying to tune to channel considered
valid by the database, you'd be correct.

I do agree; it would be nice if the frontend was more aware of what
was causing the failure, and could recover, or at least prompt the
user to choose something else.

However, in this specific instance it wasn't the backend tuning to a
channel that had gone away, rather the backend tuning to a NULL or
invalid channel, when compared against the valid channels database.

There should be a way to catch that failure, while not incorrectly
catching the "channel has gone away" issue.
