  Nautilus crashes when creating a share, more specifically when having
  selected either "Allow others to create and delete files in this folder"
  or "Guest access". In that case, Nautilus will ask if it should add the
  necessary permissions and when clicking on "Add the permissions
  automatically", Nautilus crashes. However, the share is still created
  correctly.

Nautilus crashes when creating a share, more specifically when having selected either "Allow others to create and delete files in this folder" or "Guest access". In that case, Nautilus will ask if it should add the necessary permissions and when clicking on "Add the permissions automatically", Nautilus crashes. However, the share is still created correctly.

TEST CASE:
1. Right click on an unshared folder (make sure samba and everything else has already been installed and setup) and click Sharing Properties.
2. Check the "Share this folder" checkbox
3. Check the "Guest access" checkbox
4. Click Create Share.
5. Watch as nautilus crashes and burns. If it doesn't, then the bug is fixed.
