    Bug NB#136770 - Not able to see the pictures captured with camera application after renaming the current folder.
    
    Turns out the monitor wasn't replacing the GFile (used as the key) in the
    monitors hash table after a move operation, so monitoring a newly created
    folder with the same name would fail silently.
