Crash (trap 5) when trying to negotiate peace.

I got the SmartException report below when I was trying to negotiate peace with a
race I was at war with. Unfortunately, I have not saved for many turns and I don't
know what month it was (for the newbies, autosave is done in January of each year).

This was with a Gigantic galaxy at 1280*1024*32bit.

Here is the exception report:
