Comment 18 for bug 329146

Daisuke_Ido: Could you have a look at your dmesg and see if it is libbrasero that causes things in your case, you can use the command:

cat /var/log/messages | grep nautilus

And see if you also get strings like:
[ 42.636631] nautilus[3660]: segfault at 98a0008 ip b5d9755d sp b5d85fc0 error 4 in libbrasero-media.so.0.1.1[b5d87000+1e000]

If not it may be a different issue. Or it may be that the fundamental error isn't in brasero after all...

This is NOT a definite indication, since it has to go on for a while before you see a few crashes (only very few of the hundreds of nautilus apps do crash and generate this message, and depending on the case maybe none will crash like this?)
