Since it appears to be fairly random, can you do me a favor for the next time it happens to you and list, in order, all the steps/links you went through until you got that error? Also, include the exact error message if possible. Sorry for all the steps, but it's something that I haven't seen yet and it may help to pinpoint the cause.
