    Activate the path entry when opening a directory
    
    As reported in bug 707577, opening a directory from the main window with
    the button adjacent to the path entry only updates the entry, and does
    not open the directory in the file browser. Emit the "activate" signal
    on the GtkEntry to browse to the directory after opening it.
