I assume the above is enough, but if system logs are needed, they are available: ​https://bugs.launchpad.net/mythbuntu/+bug/549352

Although this error will be handled in the jamu code it is likely that this videometadata record has been changed outside of MythVideo?. Both MythVideo? and Jamu initialize the inetref field to a value of "00000000". It is never left as Null or None, which is the situation triggering this abort.
