Bug Description

I noticed that nautilus was consuming 100% of the CPU on one of my systems. Strace revealed that it was repeatedly writing to a log file:

Killing nautilus seemed to cause the rest of the user's processes to disappear, so it looks like they had already logged off, and the nautilus process hung around because of this error.

Thanks for the bug report. This particular bug has already been reported, but feel free to report any other bugs you find. The looping bug has been workarounded in hardy by disabling the logging code, the crash is still likely due to a real bug but there is no useful details about it there
