[Bug 57210] search button does not toggle

[Killercow]

Public bug reported:

Binary package hint: nautilus

The search button in the nautilus toolbar does not toggle the location
bar to become the location bar again.

as in:

notice the folder buttons in the location bar.
Press the search button.
Notice you cannot return to the folder button view by clicking search again.

The search button should toggle this. (maybe even change its icon)

** Affects: nautilus (Ubuntu)
     Importance: Untriaged
