 This might be related to #6019, but the symptoms are a bit different.

 I have attached the full mythbackend/mythshutdown logs, but these extracts
 show the gist of the problem:

 Backend log:

 2009-01-03 10:15:18.021 Running the command to set the next scheduled
 wakeup time :-
                                                 sudo
 /usr/local/bin/mythshutdown --setwakeup 2009-01-03T10:15:00

 Mythshutdown log:

 2009-01-03 10:15:18.652 recording scheduled at: 2009-01-03T10:15:00
 2009-01-03 10:15:18.652 scheduled recording time has already passed.
 schedule deleted

 So, in summary:
 The backend decides to shut down because the next recording is scheduled
 to start in 5 minutes and 50 seconds (my idleWaitForRecordingTime is 5
 minutes).
 However, one minute later, when mythshutdown is called, it subtracts
 StartupSecsBeforeRecording (set to 300 s = 5 min) and decides that it is
 too late to set the wakeup time. To make matters worse, it does not set
 the wakeup time to the next scheduled recording - it sets no wakeup time
 at all!

 AFAICT, this will never happen as long as idleWaitForRecordingTime is at
 least a few minutes larger than StartupSecsBeforeRecording, so as a
 workaround, I will set idleWaitForRecordingTime to ten minutes.
 A possible fix could be to enforce this.
