Comment 12 for bug 150471

I'm seeing the exact same errors. Nautilus takes up 100% of the CPU and dumps a debug log file in my home folder that goes on and on (13MB!)

If I kill Nautilus then trackerd starts going crazy and I have to kill trackerd as well.
I have seen this on 2 separate computers one with desktop effects one without.
I haven't been able to find a way to reproduce this though. Seems totally random. I'll try and get a backtrace if I can.
