I'm resending this patch (this time as a unified diff) to gadgets.lisp as, apparently, it has been overlooked. Perhaps I was a bit too terse when sending the patch the first time around.

This patch is a one-line bug fix, which I believe stems from a change in standard-rectangle. Previously, rectangle coordinates were stored in slots (x1 y1 x2 y2) within standard-rectangle. In an attempt to optimize rectangle operations, these were condensed into a single coordinates slot. The problem is that an :after method on initialize-instance for gadget-output-record was never notified of said change, and was still attempting to call (with-slots (x1 x2 y1 y2) ...) on a standard rectangle. This was causing problems for me, so I swapped in a destructuring-bind on coordinates instead.
