Comment 4 for bug 32589

I frequently notice a similar thing when using the back/forward buttons. (I am using intrepid.) For example:

1. Open "File System" in tree view
2. Open /etc
3. Click on /etc/acpi to view the contents of that directory
4. Click on /dev to view the contents of that directory
5. Click the little down arrow beside /etc to collapse that directory's tree view
6. Click the back button in the toolbar to return to /etc/acpi in the main file list pane. Nautilus highlights /etc in the tree view, but doesn't expand the tree view to display the subdirectories of /etc. (This is where things begin to go wrong -- nautilus should probably expand the tree view and highlight /etc/acpi, where I actually am viewing.)
7. Click the little right arrow to expand the tree view to display the subdirectories of /etc like nautilus ought to do already.
8. Now the tree view breaks down:
  - clicking on /etc does nothing
  - clicking on subdirectories of /etc does nothing
  - clicking on other directories under "File System" does nothing
9. Furthermore, if I collapse /etc again and click around to other directories under "File System", /etc remains highlighted and even though I can navigate to other directories, clicking on /etc still does nothing. I've attached a screenshot of this behaviour (/etc remaining highlighted while I'm browsing /dev.)

Collapsing "File System" resets the tree view so it works properly again.
