[mythtvnz] Daylight Saving Reversion

[Tortise]

I don't think my box has coped with daylight saving reversion, with program listings being an hour out today.
OK, reboot.  Same.  Hmmm  Run mythfilldatabase again as it last ran at 0204am.

I get 

2010-04-04 12:28:24.164 IconData: Updating icons for sourceid: 1
2010-04-04 12:28:25.415 DB Error (programrating insert):

Also makes me wonder if its anything to do with Robin's problem?
