Prior to Monday's email, I was out of town and mostly away from the
laptop.  I can't definitively say, but it's likely I didn't have the
laptop running long enough to experience the problem.

I've since upgraded to r230510 (a few hours ago), but haven't enabled
the battery monitor in gkrellm2 yet.  I can do that later today to see
if the crash occurs again.

The hardware has not changed.
