Nautilus stopped working

[el_gallo_azul]

Nautilus stopped working earlier this morning, so I reported a bug. I restarted the computer, and Nautilus started working again. I was intermittently using Nautilus as usual. The most recent time that I tried to start and use it, it no longer works.

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu

`el_gallo_azul@W2600CR-850Pro:~$ lsb_release -rd

`

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
