Comment 19 for bug 329146

Turns out there's absolutely nothing in /var/log/messages about nautilus crashing. Interesting side effect, after about 15 minutes of leaving it running to see if I could catch a crash, my entire desktop locked up. It could be unrelated, though.

I completely removed Brasero as per Bernard's original suggestion and your follow up. To take care of thie issue, I am able to pkill nautilus after logging in. After that, Nautilus works as expected.
