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?
