Had a directory that I've used with Qimage in the past that was now crashing when I selected it and tried to scroll down. No idea when this behavior started. Found the problem by divide-and-conquer. Split it into several directories and found the file with the problem, a 1 pixel gif image. No idea why I had a 1 pixel gif image or what it was, but when I deleted it everything went back to normal. May or may not be worth worrying about but figured I'd mention it.
