 Myth backend crashed whilst the PC was idle. No frontend running.

 New installation of Ubuntu 8.10 with MythTv added via apt-get install.

 Restarted the backend without problem and can watch TV etc.

 I can provide more info or try to reproduce with guidance if requested.

 Attached is the backend log with the backtrace.

 Version below:
