Public bug reported: If I leave nautilus open to my home folder or most any folder, it uses 25% of the cpu according to top. I've not had it open most of the time, but the cpu time is at 29:05 with a system up time of 17:30:21. That is more than twice the cpu time of Xorg and more than any other process in the system. I have deleted all bookmarks, just in case. If I navigate to a folder with only a single text document in it, the high cpu use stops.
Surely this must be a bug. What is it doing? If it is scanning something, shouldn't the results be cached and the scanning stop after a while? Does nautilus try to prefetch all folders recursively or something? Also, all thumbnails in my Pictures folder show a clock or a black rectangle. In Ubuntu 14.04, I believe they showed thumbnail images. Could it be that it is trying a failing to load thumbnails?
