This is definitely a bug, and an important one. Recently I started to
suffer from these symptoms too. After starting up the computer and
running nautilus (this is important, only after running nautilus), the
gnome-settings-daemon process froze up my computer, totally. Disk
spinning. It unfroze only after a long time. Very bad experience.
After reading this bug, I finally found the cause. Thumbnails directory.
These are my measurements:
$ du -sh .thumbnails/
315M .thumbnails/
$ find .thumbnails/ | wc -l
14648
Time spent with 100% I/O load caused by g-s-d (after starting nautilus): 1min
45sec
That means every boot I had to wait 2 more minutes to be able to work
with computer.
After removing ~/.thumbnails directory the problem is gone. Now my
computer works fast again, finally.
Gnome-settings-daemon must *not* read all the thumbnails on nautilus
start. It must expect there are a lot of them!
Note: 'find' command was able to count the thumbnails quickly. But when
opening the directory with 'mc', it also took about two minutes. I
suppose that g-s-d is doing something similar to mc, like calling 'file'
on every file or similar task. That must be fixed (or otherwise g-s-d
devs should make sure there are never dozens of thousands of files in
that directory).
Please increase the priority on this.
** Changed in: gnome-settings-daemon (Ubuntu)
