    user-accounts: Prevent usage of uninitialized value
    
    gtk_widget_translate_coordinates() doesn't have to always set the
    dest_x argument. Let's initialize the argument before use to prevent
    usage of uninitialized value, which also prevents "Conditional jump
    or move depends on uninitialised value(s)" messages from valgrind.
