Steps to reproduce:
1. make a new image, e.g. 1000x1000 pixels
2. shrink the window so the image is bigger than the window
3. rotate the image by 1 degree (or -1, or probably any number)
4. press control-shift-E to get the whole image inside the windoe
5. up comes bug-buddy, gimp has crashed.


Stack trace:
I can recompile and attach a stack trace tomorrow, I'm not getting anything useful, sorry.



Other information:
if you flatten the image before zooming out, there's no problem, but if you then undo the flatten, with gimp zoomed out, it crashes.
