This was programmed eons ago; it could also have read "This should never happen, what's going on?" AFAIK you are the first to report this. Given the extremely large number, I suspect there's a problem with 64-bit math. 18446744073709551611 is 0xFFFFFFFFFFFFFFFB is -5. I'm almost sure it has to do with start and end times not being exactly what they should be (and I'm talking about RRDtool here, not what you provide as parameters). I'm sorry, I cannot debug this right now, but hopefully someone else can pick this up.
