That preference setting means that your window was on the second monitor (at position x=76, y=9). And it looks like what happened is that when you started up drracket a second time, that monitor wasn't there anymore and a bug caused it to crash instead of just moving your window to an existing monitor.
I've pushed a repair for the crash, but does that sound like a plausible scenario?
