Unfortunately, the same issue is still happening ... can't seem to
figure out what/why this would be happening, as it's always occurring
when there is no MythTV usage. XMLTV grabber appears to complete
perfectly ... about to try disabling anything/everything else just to
see what (if any) interaction may be at fault.

Again - unreportable because of obsolete packages (which weren't
involved in the crash itself) ...
