The behaviour I was expecting is exactly as if clicking 'OK' to the crop also triggered a file save. I expected that clicking the crop tool again would let me crop the now-cropped image yet further, rather than reattempt the last crop.
I suppose the easiest way to replicate this behaviour is to just hit ctrl+s just after OKing the crop, and then try another crop.
Thinking about it, giving another go at the first crop doesn't seem such a weird idea any more, but it's still completely not what I'd expect to happen on clicking the 'crop' tool.
