After seeing no kernel panics for the last few years, I have had two in the last two weeks, both while Dashboard was up when I closed the computer screen. Apart from the obvious "Don't close the screen while Dashboard is up", which I am already trying to remember, can anyone find in the log below the cause of the panic. The one below is from the second panic; the first didn't leave a log at all. I'm guessing that one of the widgets is the cause.
No recent changes apart from Security Update recently; installed more memory about six months ago, and haven't had any trouble since.
Dashboard includes: Stickies, Clock, Calculator, Maintidget, Internode Usage Meter, iStat Pro, Google, Dictionary, Address Book, Moon Phases, Weather (radocai.com).

Thanks in advance for any help.

Not much to go on from the logs. I'd put my money on 3rd party dashboard widgets.
If you can consistently reproduce the panic, remove one at a time and re-test (note that you should probably reboot after each removal to ensure it is unloaded fully). If you can't consistently reproduce the issue, then next step would be to check the Console logs to see if one of the widgets is producing some output just prior to the panic. Otherwise, remove a widget and wait and see what happens... etc.

Thanks, dangelovich.
No recently added Widgets, and it has only happened recently. However, I think you're right, and I'll try to remember to return to the desktop or other application before closing the lid - unless it starts to become regular, in which case I may have to try removing Widgets.

Thanks again.
