I think nautilus has done its thing in front of my very nose!
First I want to confirm I have noticed all the symptoms mentioned here:
-Occassionally nautilus grabs almost 100% CPU.
-When I kill it, trackerd in turn grabs CPU.
-There are more chances nautilus goes berserk if it is run as root (gksu).
-Nautilus writes enormous nautilus-debug-log.txt files with the useless message:
0x8177510 2008/01/14 11:18:03.2623 (USER): debug log dumped due to signal 11
Note: My system also has dual processor (Pentium IV hyperthreading) and, when
nautilus grabs the CPU, it alternates using both CPUs.
Let's go to the crime's scene:
-I had two nautilus' windows open one as normal user (manolo) and another as
root using my own version of gksu: XSu.
-One of the windows was showing /home/manolo/.local/share/applications, the
other (running as root) /home/manolo2/.local/share/applications.
-I had copied a file from first to second window.
-In a console (running as root), I then ran 'chown -R manolo2:manolo2
/home/manolo2/.local' to change ownership of the file just copied.
-Immediately the root-running nautilus' window went blank.
-I ran gnome-system-monitor and nautilus was using 80-90% CPU alternately from
each CPU.
-I found a nautilus-debug-log.txt in /root with current date-time.
-In the root console, I killed the berserk nautilus instance with 'kill -9
29473'.
Next follows the relevant part of .xsession-errors:

The XSu instance running the rogue nautilus is 'XSu-29395'. Cleaned of other
irrelevant messages:

Hope it helps!
