I start nautilus from the command line and do the following:

1) Click on Edit item on menu bar
2) Click on Preferences
3) Click on Sidebar Panel
4) Check and then uncheck "Show only folders (no filers) in the tree"
5) Click on Close button in Preferences dialog
6) Click on File item on menubar
7) Click on Close Window

In session-properties window remove nautilus entry, i..e Alt+r Alt+a after
selecting nautilus.

Warning messages are output.
