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'.
