Greg, if you have more information about the circumstances or if you can reproduce with 4.3.0 I20130428-2000 or later, then please reopen this bug.

I don't have any specific information since this error just (seemingly) randomly happened. I'll try to provide additional information if it occurs again. I have been getting many intermittent problems with both 4.2 and 4.3 and report them as I see them.
