    file chooser: Ensure the path bar is initialized
    
    There are some cases where we can end up showing the path
    bar without ever setting a file on it. One example is:
    1) Open file chooser
    2) Hit ~
    3) Hit Ctrl-L
    While this is a bit of a workaround, at least it makes sure
    that we never end up with an empty space where the path bar
    is supposed to be.
